Businesses switching from manual phone calls to automated text messaging can save businesses up to $3,266.28 annually, representing a 77% reduction in communication costs. These significant savings in time and money make automated text messaging a powerful tool for improving customer engagement and streamlining operations. 

This guide will provide step-by-step instructions on setting up automated text messages and creating SMS drip campaigns to maximize efficiency and results.

What are automated text messages?

Automated text messages are pre-scheduled or trigger-based messages sent to customers through advanced platforms or APIs. Unlike manual texting, these messages are designed to streamline communication, ensuring timely and consistent outreach without requiring constant human intervention. Whether it’s a reminder about an upcoming appointment, a shipping update, or a personalized promotional offer, automated text messaging allows businesses to engage their customers more efficiently.

Common use cases:

• Appointment reminders: Ensuring that customers never forget an upcoming service. 
• Marketing campaigns: Sending promotional offers or product updates to subscribers.
• Customer support: Sending automated responses to inquiries or frequently asked questions.
• Event updates: Notifying customers of event details, cancellations, or promotions.
• Order notifications: Updating customers about order confirmations, shipping statuses, and delivery.

Key benefits of automated text messages:

• Increased efficiency: Automating tasks such as appointment reminders, follow-ups, and order updates allows your team to focus on more complex inquiries, boosting overall productivity.
• Reduced human error: Automation ensures consistency in messaging and eliminates mistakes that may occur with manual texting, delivering accurate and timely communication every time.
• Consistent messaging: Automated systems send messages promptly, ensuring timely communication without delays. 
• Personalization: Automated systems can integrate customer data, such as past purchases or location, to send personalized messages.
• Improved engagement: Timely, relevant messages—such as time-sensitive offers—encourage customers to take immediate action, leading to higher conversions and stronger relationships.
• Cost and time savings: By automating routine messages, businesses can save valuable employee time and reduce operational costs. 
• Accessibility: Automated text messages ensure quick communication with customers. 

How to set up automated text messages

Setting up automated text messages is simple and efficient, thanks to the variety of platforms available. Here’s a clear step-by-step guide to help you get started:

1. Selecting the right platform

Choosinge a reliable SMS automation platform, such as Plivo, can provide the necessary tools to send bulk texts, manage contacts, and track message performance.

2. Defining triggers

Automated messages are often triggered by specific customer actions or events, such as:

• A customer making a purchase
• A user subscribing to your newsletter
• A scheduled appointment or event
• A cart abandonment on an e-commerce site

For example, if a customer subscribes to your service, an automatic text can be triggered to confirm their subscription or provide a welcome message.

3. Crafting effective messages

When creating automated messages, make sure the content is:

• Clear and concise: Ensure your message gets straight to the point.
• Actionable: Include a clear call-to-action (CTA), such as “Click here to claim your discount.”
• Personalized: Use customer data to tailor messages, such as including their first name or past purchase details.

4. Scheduling for optimal impact

Consider when your customers are most likely to read your messages. Sending an SMS at the right time (e.g., early afternoon for most people) can significantly increase open rates and engagement. Additionally, ensure your messages aren’t sent too frequently to avoid overwhelming customers.

5. Measuring and optimizing success

To evaluate the success of your automated text campaigns, track key metrics:

• Open rates: The percentage of recipients who open your message.
• Click-through rates (CTR): The percentage of recipients who click a link within your text message.
• Conversion rates: The percentage of recipients who take the desired action (e.g., making a purchase, signing up).
• Using analytics: Most SMS platforms offer analytics to monitor these metrics. Use this data to refine your campaigns and improve engagement.

SMS drip campaigns

SMS drip campaigns are a sequence of automated text messages sent over time based on a customer’s interactions or behavior. The goal is to guide customers through a predefined journey—whether it’s converting leads into customers, nurturing relationships, or encouraging repeat purchases.

How to create SMS drip campaigns:

1. Define the objective: What do you want your campaign to achieve? For example, do you want to promote a new product or nurture customer loyalty?
2. Segment your audience: Based on customer data, segment your audience for targeted campaigns. Segmenting helps ensure you’re sending relevant messages to the right customers.
3. Map out the journey: Create a sequence of messages that guide your customers step by step, ensuring each message aligns with the campaign’s goal.
4. Test and optimize: Regularly test your messages for effectiveness and make adjustments based on open rates, response rates, and customer feedback.

Legal compliance and best practices

When sending automated text messages, compliance with various laws and regulations is essential to avoid penalties and maintain trust with your customers. The two key regulations you need to be aware of are the Telephone Consumer Protection Act (TCPA) and General Data Protection Regulation (GDPR).

1. TCPA (Telephone Consumer Protection Act): This regulation restricts businesses from sending unsolicited promotional text messages to consumers. To comply, ensure that you:

• Obtain explicit consent before sending marketing messages.
• Provide clear instructions for opting out (e.g., "Reply STOP to unsubscribe").
• Only send messages within reasonable hours (typically between 8 AM and 9 PM local time).
• Avoid using automated dialing systems for marketing calls without prior consent.

2. GDPR (General Data Protection Regulation): If you’re operating in the EU or dealing with EU-based customers, GDPR applies. It emphasizes transparency, security, and consent regarding the processing of personal data. Key points to remember include:

• Collecting explicit consent from individuals before sending marketing communications.
• Giving users the ability to easily withdraw consent at any time.

Protecting and securing any personal data you collect from your customers.

Tools for automating text messages

When selecting a tool, consider:

• Business size: Small businesses may need simpler tools, while larger companies might require scalable platforms.
• Budget: Different tools offer varying pricing plans based on the number of messages or features.
• Ease of use: Look for a platform that aligns with your technical capabilities.

Several platforms provide excellent features for automating text messages, from basic functionality to more advanced workflows. Here are some popular options:

You’ve just hosted an event that took months to plan. The turnout was fantastic, the conversations flowed, and your team nailed every detail. But now comes the real challenge—following up. How do you craft a thank you message for attending the event that feels personal and leaves a lasting impression? 

What's the best way to show genuine appreciation and build a stronger connection, avoiding generic thank-yous? It's not simply about being courteous; it's about strategically strengthening connections, fostering trust, and ensuring long-term brand recall. If you’re stuck staring at a blank screen, wondering where to start, don’t worry—you’re not alone. 

This blog highlights how to get it right with practical tips and examples to inspire your next move. 

The importance of thank you messages after events

After organizing an event, following up with a thank you message can make all the difference. It’s a simple yet effective way to maintain relationships and set the stage for future success. Here’s why these messages are crucial:

1. Impact on future events and lasting connections

A well-crafted thank you message strengthens your relationship with attendees and keeps the door open for future events. It reminds them of the value they received and leaves a positive impression. For instance, a tech startup might send a thank you email to event participants and include a sneak peek at their upcoming product launch, keeping the audience engaged for future interactions.

2. Expressing appreciation for attendees' time and resources

Your attendees are busy individuals. A thank you message shows you recognize and appreciate the time and effort they put into attending. It can be as simple as acknowledging how their presence helped make the event a success. Consider this: after hosting a webinar, a product manager could send a quick thank you note along with a link to additional resources, valuing their time spent and making it easy to keep the conversation going.

3. Building positive relationships and loyalty

When you show gratitude, it creates a sense of reciprocity. Attendees are more likely to engage with your future events or offerings when they feel valued. For example, a software company might send a personalized thank you message to clients who attended a product demo. Offering a discount for future purchases can be a way to nurture loyalty and ensure they’re more likely to return.

4. Reinforcing the event’s message and key takeaways

Thank you messages can reinforce the core messages and insights from your event. Highlighting key points helps attendees recall the value they received. For instance, a business consultant could send a thank you email post-seminar, summarizing the most important strategies discussed, leaving attendees with a lasting impression of the event’s value.

5. Enhancing brand reputation

A thoughtful thank you message helps position your brand as considerate and customer-centric. It shows that your company goes beyond the event and is committed to maintaining long-term connections. For example, a company hosting a developer conference might send a message after the event, expressing gratitude and inviting feedback for improvement, making attendees feel heard and valued.

6. Encouraging feedback and continuous improvement

A thank you message can include a call to action, like asking attendees to share feedback. This demonstrates your care for their feedback and contributes to the improvement of future events. Imagine a business sending a follow-up survey after a trade show, offering attendees the chance to provide suggestions or highlight areas of interest for upcoming events.

So, how do you craft a thank you message that truly resonates? Let's explore the essential elements to include.

Must-have elements in your thank you message

A thank you message is about reinforcing relationships and showing genuine appreciation, not simply about being polite. Here’s a quick breakdown of the core elements that should always be part of your message:

Every element of your thank-you message helps turn a simple gesture into a meaningful connection. It fosters trust, encourages ongoing engagement, and highlights the value of your relationship with the attendees.

These must-have elements form a strong foundation, but let's discuss some best practices to help you craft even more impactful thank yous.

Best practices for crafting thank you messages

Creating a thank-you message that truly resonates goes beyond a simple thank-you. It’s about strengthening your relationship with attendees and keeping the value of your event front and center. Here's how you can nail it every time.

• Personalize the Message

Begin by addressing the attendee by name. This makes the message feel more genuine and tailored to them, not just a mass email. If you hosted an event for a specific product or feature, mention how their attendance contributed to its success. 

For instance, “Thank you for attending our product demo on X. Your insights truly helped shape our conversation.”

• Keep it Short and Sweet

People are busy. A concise thank you message that gets to the point is far more effective than one that rambles. Get your main message across in just a few sentences, focusing on appreciation and next steps. 

For example, "Thanks for attending our webinar on improving customer support with AI. Keep an eye out for our upcoming sessions on AI-driven solutions!"

• Mention the Event's Impact

Reinforce the value of the event they just attended. Whether it was the knowledge shared, the network built, or the solutions discussed, ensure they feel that their time was well spent. 

If you're in the education technology industry, a quick statement like, "We hope the insights from the session help you enhance your learning platform," can make a big impact. It shows you understand their needs and reinforces the value of your offering.

• Include a Call to Action (CTA)

Don't leave them hanging. After thanking them, prompt them to take the next step. This could be exploring your solutions further, joining your next event, or connecting on social media. 

A simple “Check out our upcoming events to keep the conversation going” can encourage future engagement.

• Timeliness is Key

Timing plays a huge role in how well your message lands. Send the thank you note promptly after the event—ideally within 24-48 hours. The quicker you reach out, the more likely they are to remember and appreciate the event. Make it part of your automated post-event follow-up.

• Make it Authentic

Authenticity is what builds trust. Be genuine and avoid sounding too robotic or scripted. Personal anecdotes or simple statements like, “It was a pleasure having you with us!” can create a deeper connection.

• Offer Future Value 

Let attendees know you’ll continue offering value post-event. Perhaps it's a special offer, a follow-up resource, or an invitation to a community. For example, “As a thank you, enjoy an exclusive 10% discount on your next purchase to show our appreciation.” This keeps them engaged and eager for future opportunities with your brand.

To show you what these best practices look like in practice, let's explore some examples of effective thank you messages.

Examples of impactful thank you messages

1. Thanking attendees and inviting them to share their photos on social media

“Thank you for joining us at [Event Name]! We hope you found the event valuable and insightful. If you snapped any great photos or had memorable moments, we’d love to see them! Share on social media and tag us for a chance to win free tickets to our next event.
We truly appreciate your time and support. Looking forward to connecting again soon!”

2. Gathering feedback and expressing gratitude

“Thank you for attending [Event Name]! Your presence truly made a difference. If you enjoyed the event, we'd appreciate it if you could leave a review here [LINK]. Your feedback helps us improve and ensures we continue delivering valuable experiences. We’re grateful for your support!”

3. Appreciating insightful contributions and support

“Thank you for attending [Event Name] and sharing your valuable insights. Your input truly made the event better. We hope you found it to be a meaningful experience. Your support is greatly appreciated, and we look forward to more collaboration in the future.”

4. Reaching out by name to encourage attendee feedback

“Hi [Attendee Name], thanks for attending our event! Your presence made a real difference, and we hope you found it valuable. If you have any feedback, we’d love to hear it. Share your thoughts here: [LINK]. Looking forward to having you with us again soon!”

5. A heartfelt thank you and a glimpse into what's next

“Thank you for attending [Event Name]! Your time and participation made the event special. We hope you gained valuable insights and connected with peers. We’re excited to welcome you to our future events!”

6. Thanking for enthusiastic participation

“[ATTENDEE NAME], thank you for your active and energetic participation at [EVENT NAME]. It wouldn't have been the same without you.”

7. Thanking attendees for making the event a success

"Your participation in [Event Name] meant a lot to us. You helped make the event special. We’re grateful for your time."

These examples provide a good starting point, but how can you ensure your thank you messages are received with sincerity? Let's discuss different delivery methods.

Methods to deliver genuine thank-you messages

In a business context, thank you messages show appreciation, encourage future engagement, and strengthen your brand’s reputation. Let’s explore some methods for delivering thank-you messages that resonate and leave a lasting impact.

• Personalized emails

A personalized email is one of the most direct ways to express gratitude. Attendees feel valued when you address them by name and reference specific parts of the event, showing appreciation for their time and input.

• SMS/Text messages

Given the rapid advancements, an SMS thank-you message offers a quick and direct way to show appreciation. This method is particularly effective for busy professionals who may not have the time to read long emails. Sending a brief text message that acknowledges their time and participation can leave a positive impression. 

• Social media acknowledgments

Social media platforms are a great way to thank attendees or clients publicly. Mentioning their participation or tagging them accomplishes two things: it shows appreciation and strengthens your social proof. Sharing event highlights and thanking specific attendees for their insights can help increase visibility and engagement. 

• Video messages

A video message can make your thank-you feel more personal and engaging. It helps convey warmth and sincerity, making the recipient feel valued. Whether it’s a simple thank-you or a deeper reflection on the event, video can offer a unique touch. 

• Handwritten notes

Though more traditional, handwritten notes add a personal touch that digital methods can’t replicate. A brief note, sent by mail, thanking someone for their participation in an event, can stand out in the digital age. 

• Event follow-up surveys with a thank you

Including a thank-you message in your post-event survey is a great way to both show gratitude and gather valuable feedback. After an event on IVR systems, for instance, a quick “thank you for your participation” at the start of your survey helps the respondent feel appreciated before they share their thoughts. The survey itself becomes a chance to strengthen your relationship while gathering insights to improve future events.

• In-app or platform messages

If you're offering e-commerce solutions, sending a quick thank-you message after a customer completes a purchase or places an order shows genuine appreciation. This helps you connect with them while they’re engaged with your platform.

If you’ve ever faced the frustrating issue of MMS messages not sending on your Android device, you’re not alone. Whether you’re trying to share photos, videos, or other multimedia content, MMS can sometimes be unreliable, leaving you wondering what went wrong.

For businesses, the impact of failed MMS messages is even more critical. It can disrupt customer communications, delay crucial updates, or derail high-stakes marketing campaigns, leading to revenue loss and customer dissatisfaction.

Understanding why MMS issues occur is the first step toward resolving them. In this guide, we’ll break down the most common causes of MMS failures on Android devices and practical solutions to get things back on track. Plus, we’ll explore how Plivo’s MMS API offers a reliable, scalable solution to overcome these challenges, ensuring seamless multimedia messaging for businesses.

Why do MMS issues occur on Android, and how can you resolve them?

Multimedia Messaging Service (MMS) is an indispensable feature for sharing rich media like photos, videos, and audio. However, Android users often face issues with MMS messages not sending, delayed deliveries, and unsupported file types. These problems can be frustrating for individuals and disastrous for businesses relying on seamless multimedia communication.

Addressing these problems requires a deep dive into the most common causes and effective fixes. Here's a detailed look at why MMS messages not sending is a common issue and practical steps to resolve them:

1. File size restrictions

Why it happens: Mobile carriers impose limits on the size of MMS attachments, usually between 300KB and 1MB. If these limits are exceeded, mms messages not sending becomes a frequent problem.

Solution: Before sending an MMS, check the size of your attachments. Use built-in gallery tools or third-party apps to resize or compress images and videos while maintaining acceptable quality.

For Businesses:
When a business launches a marketing campaign using MMS, ensuring that the content fits within these size constraints is crucial. A failure to do so can result in MMS messages not sending, affecting campaign reach and engagement. Plivo’s MMS API helps businesses by:

• Automated image resizing: Automatically optimizing multimedia content to meet carrier requirements.
• Reliable scaling: Supporting large-scale campaigns without manual intervention, ensuring high delivery success rates.

2. Incorrect APN (Access Point Name) settings

Why it happens: MMS relies on APN settings to connect to your carrier’s network. Incorrect or outdated APN settings can block the network connection necessary for MMS, leading to MMS messages not sending.

Solution: Verify your APN details by navigating to Settings > Network & Internet > Mobile Network > Access Point Names. Compare the settings with those provided by your carrier and adjust as necessary. If needed, reset the APN to its default settings.

Practical Tip: Many users overlook APN settings or are unaware of their significance. Providing clear guidance or automated tools to update these settings can significantly reduce the incidence of MMS messages not sending.

3. Mobile data disabled

Why it happens: Unlike regular SMS, MMS requires an active mobile data connection. If mobile data is turned off, it results in MMS messages not sending.

Solution: Ensure mobile data is enabled via Settings > Network & Internet > Mobile Data. Additionally, check with your carrier to confirm your plan includes MMS services and sufficient data allowance. This simple check can often resolve issues of MMS messages not sending.

Plivo Advantage: Plivo’s message queuing automatically retries failed messages when network conditions improve, ensuring higher delivery rates for your business communications.

4. Background data restrictions

Why it happens: Android’s background data restriction settings may prevent your messaging app from handling MMS traffic, leading to MMS messages not sending.

Solution: Disable data restrictions for your messaging app. Go to Settings > Apps > [Your Messaging App] > Data Usage, and allow both background and unrestricted data access.

Example: If a user has enabled data-saving mode while traveling, their messaging apps like Google Messages or Samsung Messages may struggle to download MMS attachments, leading to failed deliveries.

Business Impact:
For businesses relying on MMS for customer engagement, ensuring users have unrestricted data access is crucial for message delivery. Plivo’s MMS API offers message tracking and retry capabilities to minimize data-related failures and optimize delivery rates.

5. Outdated software

Why it happens: Running an outdated Android version or messaging app may cause compatibility issues with MMS protocols.

Solution: Regularly update your device and apps. Check for system updates under Settings > System > Software Update and update your messaging app through the Google Play Store.

6. Weak network signal

Why it happens: MMS relies on a strong and stable carrier network connection. Poor signal strength can disrupt the transfer of multimedia messages.

Solution: Assess your signal strength by observing the network bars on your device. If the signal is weak, try moving to an area with better reception. Adjusting the network mode under Settings > Network & Internet > Mobile Network > Preferred Network Type may also improve connectivity.

MMS for Businesses: Key benefits and how it works

For businesses, MMS is more than just a way to share pictures—it’s a critical tool for marketing, customer support, and internal communications. However, when MMS issues arise, they can significantly disrupt operations, leading to missed opportunities and reduced customer satisfaction.

Why Businesses Rely on MMS

Unlike traditional SMS, MMS supports rich multimedia content such as images, videos, and audio, making it an effective communication tool for businesses across various industries. Whether it’s promoting a product, sharing time-sensitive alerts, or offering personalized support, MMS helps create engaging and impactful customer interactions.

Some Business Use Cases of MMS:

1. Marketing and Promotions
   
   • Send visually engaging content like product launches, discount offers, and event invitations to capture attention and drive conversions.
   • Example: A retail brand uses MMS to share promotional videos and coupon codes, boosting customer engagement rates by 45%.
2. Customer Support Enhancement
   
   • Resolve customer queries faster by sharing step-by-step instructions through images or video clips.
   • Example: A telecom provider uses MMS to send visual troubleshooting guides, reducing support call volumes.
3. Operational Efficiency and Notifications
   
   • Share delivery updates, appointment reminders, and internal communication alerts with employees or customers.
   • Example: A logistics company sends MMS updates with delivery schedules and driver details.

How Plivo helps you stay ahead with reliable MMS solutions

While these troubleshooting steps work for individual users, businesses face a different set of challenges. Ensuring seamless multimedia communication at scale requires a robust, reliable platform. That’s where Plivo’s MMS API shines.

Text messaging is a cornerstone of modern business communication, from sending order updates to delivering critical customer service alerts. However, when texts fail to send, it disrupts operations, damages customer relationships, and hampers business efficiency. In fact, studies indicate that 93% of U.S. consumers have signed up to receive texts from businesses or are interested in doing so as of 2023, highlighting the importance of SMS for immediate customer communication. Delivery issues can lead to significant losses in customer trust.

For industries like retail, healthcare, and fintech, timely communication is crucial. Imagine a healthcare provider failing to send an appointment reminder or a retailer missing a flash sale notification—these lapses can result in missed opportunities and dissatisfied customers.

This article explores the common reasons for text delivery failures and offers practical tips to resolve these issues, ensuring your business maintains seamless communication.

Common reasons texts aren't sending

For businesses using SMS messaging, here are some key reasons why texts may not be delivering:

1. Improper number registration

Mobile carriers require business phone numbers to be registered before texting customers. In the U.S., 10-digit local numbers (10DLC) must be registered with The Campaign Registry, while toll-free numbers need registration through service providers like Plivo or Twilio. Unregistered numbers may experience message filtering or blocking by carriers.

2. Content flagged by carrier filters

Carriers employ sophisticated filters to block messages containing potentially problematic content. These filters help protect consumers from spam, fraud, and inappropriate material. Here's a breakdown of what typically gets flagged:

• SHAFT content (sex, hate, alcohol, firearms, tobacco)
• Other prohibited topics (profanity, cannabis, high-risk financial services)
• Suspicious links or link shorteners
• Excessive spelling/grammatical errors

3. Sending patterns triggering filters

Carrier filters are designed to detect and prevent spam-like behavior in SMS messaging. Certain sending patterns can trigger these filters, potentially leading to blocked messages or penalties for the sender. 

• Repetitive messaging: Sending identical or very similar messages repeatedly, especially without receiving replies, can be flagged as potential spam.
• High-volume sending: Dispatching a large number of messages in a short time frame can overwhelm carrier systems and trigger spam filters.
• Frequency considerations: While there's no universal rule for daily text limits, carriers monitor the frequency of messages from individual senders.
• Time-based patterns: Sending messages at odd hours or in rapid succession can raise red flags with carrier filtering systems.
• Lack of engagement: A low response rate or high number of opt-outs can indicate to carriers that messages may be unwanted.

4. International messaging complexities

International messaging complexities present significant challenges for businesses engaging in cross-border SMS communications.

Regulatory Variations:

• Country-specific rules: Each nation has its own set of regulations governing SMS marketing and business communications.
• Consent requirements: Opt-in procedures and consent management vary widely between jurisdictions.
• Content restrictions: Some countries have stricter content guidelines than others, particularly for sensitive topics.

Examples of country-specific regulations:

• Canada: Canadian numbers can only be texted using toll-free numbers for business communications.
• European Union: GDPR imposes strict data protection and consent requirements for messaging.
• China: All SMS content must be pre-approved by Chinese authorities before sending.
• Australia: The Spam Act 2003 requires explicit consent and easy opt-out methods for commercial messages.

Technical considerations:

• Number formatting: Different countries use various formats for phone numbers, which can affect message routing.
• Character encoding: Some languages require specific character sets, impacting message length and delivery.
• Time zones: Sending times must be carefully managed to comply with local regulations on acceptable hours for business communications.

5. Technical issues

Hardware problems with carriers or service disruptions with SMS providers can significantly impact message delivery. Here are some carrier infrastructure issues:

• Network outages: Carriers may experience temporary or prolonged outages due to equipment failures, power issues, or natural disasters. During these periods, SMS messages cannot be routed through the affected areas.
• Capacity overload: During high-traffic periods (e.g., holidays, major events), carrier networks may become congested, leading to delayed or failed message deliveries.
• Hardware failures: Critical components like SMS centers (SMSCs) or routing equipment may malfunction, disrupting the flow of messages.
• Maintenance windows: Scheduled maintenance on carrier networks can temporarily halt or slow down message processing.

SMS provider service disruptions:

• API outages: If an SMS provider's API experiences downtime, messages sent through that service will fail to be delivered.
• Server issues: Problems with an SMS provider's servers (e.g., database failures, software bugs) can prevent message processing and delivery.
• Routing problems: Issues with message routing algorithms or connectivity between the provider and carriers can cause delivery failures.
• Third-party dependencies: SMS providers often rely on multiple carriers and other services. Issues with these dependencies can cascade into delivery problems.

6. Recipient-side issues

Recipient-side issues can significantly impact SMS delivery success. 

Invalid or deactivated phone numbers:

Experts project the global Voice over Internet Protocol (VoIP) services market to reach USD 361.53 billion by 2031. This growth is driven by businesses seeking more flexible, cost-effective solutions for their communication needs. However, to meet customer expectations, VoIP call quality must remain front and center.

With a staggering 93% of customers expecting their issue to be resolved on the first call, businesses are under increasing pressure to provide efficient customer service.

Good VoIP call quality can make or break the customer experience. In this blog post, we will explore 11 steps to ensure your VoIP calls show just how committed you are to great service.

The inside scoop on call quality

Call quality refers to the clarity and reliability of a voice call when using a VoIP phone system. It includes factors like audio clarity, the absence of delays or dropped calls, and the communication flow between the caller and agent.

More than technical metrics, good VoIP call quality ensures a smooth experience, customer satisfaction, and business success.

Poor call quality often results from choppy audio or dropped calls caused by network congestion, insufficient bandwidth, or a poor internet connection. For more in-depth insights, let’s understand the process of VoIP data transmission and what affects the call quality in a VoIP system.

Process of VoIP data transmission over calls

VoIP calls turn sound waves into digital signals and packetize them for transmission before reconverting them into sound waves as they reach the other end. Here are four key steps involved in data transmission:

• Signal conversion: When you speak into the VoIP device, it captures your voice as an analog signal. VoIP codecs turn the analog signal into digital data and break it into small digital packets.
• Data transmission: These digital packets are then transmitted over the internet. Every data packet travels the fastest route possible.
• Signal reassembly: As it reaches the other end, the VoIP system decodes and reassembles the data packets into an analog audio stream.
• Protocols and codecs: Session initiation protocol (SIP) handles the call lifecycle from connection to end, while an audio codec compresses and decompresses spoken words.

The source(s) of your VoIP problems

VoIP call quality issues arise when there’s a failure in packet transmission.

As mentioned, analog sound gets converted to packetized digital data. These voice packets travel through the user’s device, the router, the VoIP provider’s media server, and the carrier network before reaching the recipient's device.

Each step in this process presents an opportunity for call quality issues. Network issues such as packet loss, bandwidth usage, and insufficient internet connection speed can result in poor call quality.

To improve VoIP call quality, you’ll need to ensure smooth packet transmission. While you cannot control issues on the recipient's end, you can follow best practices for call quality for your browser software development kit (SDK).

Types of VoIP call quality issues

Here’s a list of some common call quality issues faced in VoIP systems.

• Audio latency: Latency can cause delays in audio delivery, leading to awkward timing where participants may speak over each other.
• Jitter: Jitter in VoIP calls means skipped audio or silent gaps caused by irregular packet delivery, which disrupts the rhythm of conversation.
• Packet loss: Missing or delayed data packets, often due to bandwidth restrictions or unreliable internet connections, can result in missing audio.
• Poor network connections: Weak or unstable internet connections can degrade call quality, causing latency, jitter, and packet loss.
• Codecs used: Low-bandwidth codecs may compromise audio quality.
• Quality of Service (QoS) policies: QoS settings that don’t prioritize VoIP traffic cause network congestion, which negatively impacts call quality.

How to improve VoIP call quality when hiccups strike

Here are 11 steps to enhance VoIP performance.

1. Monitor call quality

Monitoring VoIP call quality is essential for identifying and resolving issues.

Track call quality metrics such as jitter, packet loss, and mean opinion scores (MOS) with tools that give visibility into network health. You can also enable logging for individual devices to track events of errors. Network management software can help monitor bandwidth usage.

Improving VoIP call quality also involves enhancing the customer experience once calls are connected. Actively respond to complaints about choppy audio, echoes, or dropped calls.

Consider upgrading VoIP equipment and implementing an effective IVR (interactive voice response) system to streamline customer interactions. When cross-referenced with objective metrics, subjective issues can help identify and resolve call quality problems.

For instance, VoIP service providers like Plivo offer Call Insights to track key metrics.

Plivo’s Call Insights help assess call quality for packet analysis of voice traffic. The Call Summary Dashboard summarizes performance data and segments calls by subaccount, geo-location, hangup details, carrier network, and device metadata.

It also lets you collect end users’ feedback with the Call Quality Feedback API to determine the root cause of frequently reported issues.

Using this feature, you can obtain detailed call statistics of each call to troubleshoot VoIP issues. Additionally, it becomes convenient to discover patterns by drilling down the key vectors influencing quality and correlate them with audio quality issues.

2. Upgrade your router

Most small and medium business routers are basic and require little maintenance. If you're scaling your business and experiencing VoIP call issues, consider upgrading your router. Choose a router compatible with SIP and VoIP for better call quality and high-speed connectivity.

An upgraded router offers advanced features, such as QoS settings to prioritize VoIP traffic, implement jitter buffers, and segment voice traffic with a virtual local area network (VLAN). These features ensure smoother voice communication by reducing latency and packet loss.

3. Increase bandwidth

Voice packets pass through routers and servers before reaching the other end, and any congestion in the route can degrade VoIP call quality.

Network congestion occurs when multiple applications use bandwidth simultaneously, much like traffic on a busy highway, slowing down communication.

Opt for higher bandwidth if your network cannot handle several devices and users. This offers speedier data transfer when multiple users or devices are logged in simultaneously, lowering congestion and increasing overall VoIP call quality.

4. Configure QoS

Another way to beat congestion is to prioritize VoIP calls on your network.

Network prioritization involves adding dedicated lanes for VoIP calls, ensuring that voice packets have the bandwidth to travel smoothly.

Configure QoS to prioritize VoIP calls over other data types on your network to reduce VoIP latency and packet loss. Setting up QoS for VoIP involves configuring the router’s bandwidth settings to optimize VoIP network settings, which may require assistance from an IT professional.

5. Set up a jitter buffer

Another way to beat network congestion or packet loss is by setting up a jitter buffer. A jitter buffer helps smooth VoIP call quality by collecting, storing, and sending voice packets at even intervals.

While the jitter buffer may introduce a slight delay due to packet processing time, it will reduce interruptions caused by packet delivery inconsistencies. More stable and clear voice communication significantly enhances the call experience.

6. Segment traffic with a VLAN

A VLAN enables devices of any geographical location to share a connection to specific servers.

Segmenting voice traffic with a VLAN prioritizes VoIP calls over other data, improving call quality even in large or distributed networks. Therefore, VLAN is a network prioritization method for businesses operating in multiple locations or operating a VoIP call system with remote workers.

Most enterprise networks support VLAN configuration, so check with your network provider to see if this option is available.

7. Purchase a high-quality headset

Headsets can also be a VoIP call quality hazard as they may be prone to connectivity and sound issues.

Some headsets may not be compatible with certain operating systems, while some have advanced features that detect long silences and disconnects. In addition, certain headsets also have microphones that pick up incoming audio, prioritize one-way audio, and cause sound distortion.

Purchase high-quality wired VoIP headsets as wireless headsets can have adapter and driver configuration issues that cause static or white noise. What’s more, headsets with noise-canceling features can ensure call quality even in noisy environments.

8. Choose the right codec

The codec you choose for your VoIP phone system will determine bandwidth usage and affect call quality. Codecs like G.711 offer excellent sound quality but consume more bandwidth. Others, like G.729, focus on maximizing compression to reduce bandwidth usage at the cost of some audio quality.

Consider the impact of these codecs during peak usage times — G.729 may result in a few lost packets. Still, it may provide better VoIP bandwidth management, improving overall call quality.

9. Avoid WiFi

WiFi coverage is often spotty, especially in larger office spaces with network congestion. It wasn’t designed for real-time applications like VoIP, and multiple devices on the network can compete for bandwidth, degrading call quality.

If you’re facing VoIP call quality issues, consider a wired ethernet connection over WiFi for a stable internet connection.

Ethernet connections help avoid interference from other devices, such as smartphones and microwaves, which can cause crackling or humming sounds during calls.

10. Prioritize mobile phone traffic

VoIP systems offer the flexibility of mobile apps, allowing users to make VoIP calls from mobile phones. While some features may be limited to desktop apps, mobile VoIP calls provide remote work advantages for sales and support teams.

In terms of voice quality, VoIP calls made on a mobile phone are similar to voice-over-IP methods like FaceTime audio.

A strong LTE connection is usually sufficient for maintaining high VoIP call quality. You can prioritize VoIP traffic on your mobile device by disabling cellular data for other apps to improve VoIP call quality.

Pro Tip: Avoid relying on shared internet connections due to potential network congestion when using public WiFi.

11. Improve call handling with a well-designed IVR

A well-designed IVR system is essential for improving VoIP call quality and enhancing customer satisfaction.

With Plivo’s PreAnswer feature, you can engage callers before they connect to a live agent. Offering helpful information, promotions, or answering FAQs while they wait keeps them informed and reduces the strain on agents. This leads to shorter wait times, fewer call drops, and a hassle-free experience.

Creating an intuitive IVR menu prevents confusion and frustration. It’s also vital in businesses that handle sensitive information like banking. Integrate clear, concise, and easy-to-navigate IVR menus to reduce call wait times and improve customer satisfaction significantly.

Keep testing and optimizing the IVR for peak traffic to ensure quick routing and smooth call handling during busy times.

Voice AI technology drives a $12 billion market projected to quadruple by 2029. Major companies such as Amazon, Apple, and Google have already demonstrated its potential. Today, voice AI is much more than simple command systems and preset responses — it handles complex conversations, grasps context, and provides human-like interactions at scale.

For business leaders and developers, this translates to automated customer support, multilingual communication, and accessible digital experiences. With 157 million users expected to rely on voice agents by 2026, companies need to integrate Voice AI to stay competitive.

Here's your guide to voice AI's components, applications, and business impact.

What is an AI voice?

AI voice is a technology that simulates human-like speech from text inputs or other sources using deep learning models trained on real voice data. It creates natural-sounding voices that can be customized based on gender, age, accent, and emotions.

Using AI voice agents in businesses means you slash support costs and offer 24/7 availability — like Bank of America's virtual assistant Erica, which handles over 2 billion customer interactions.

With AI voice, you can automate customer service, handle high call volumes, and provide consistent service quality across all customer interactions through voice bots and IVR systems. Modern AI voice tools analyze speech context, understand user intent, and generate appropriate responses without human intervention.

How do AI voices work: A detailed breakdown

AI voice systems convert human speech into actionable computer responses through five core components — each handles a specific task in the voice interaction chain. Here’s a walkthrough of these components.

Automatic speech recognition (ASR)

                                                                                                                                         Source

ASR is the first step to speech-to-text conversion. When users speak to a voice assistant or call customer service, ASR converts their speech into text in a few steps:

• Audio capture: First, ASR captures audio through your microphone and splits it into tiny segments of 10-20 milliseconds. It then converts these segments into spectrograms — visual maps that show sound frequencies over time.
• Sound analysis: Deep learning models analyze these spectrograms and match them to phonemes (basic speech units). The system's neural networks break down the audio, compare it against existing speech patterns, and identify matching words from its data pool.
• Noise management: ASR filters out background noise and audio glitches that could affect accuracy before processing the text.
• Speech processing: Finally, a language model combines the identified phonemes into words and sentences. It checks the probability of word combinations to ensure that the transcription makes sense in the user's target language.

Modern ASR handles diverse accents, speaking speeds, and background conditions. The flexibility makes it effective for customer service, voice commands, and automatic transcription.

Natural language processing (NLP)

Next, NLP converts the text from ASR into meaningful actions. Here's how:

• Text breakdown: NLP splits user input into analyzable chunks and runs a syntactic analysis (checking word patterns and sentence structure). 
• Meaning extraction: The system collects the core meaning from text and analyzes it semantically (context and word relationships) to understand the user intent.
• Entity recognition: NLP spots and labels key information like customer names, account numbers, dates, and locations to process requests.
• Intent classification: The system identifies the specific action a user wants to take, whether it's checking a balance, scheduling an appointment, or filing a complaint.
• Sentiment analysis: NLP looks at word choice and phrasing to gauge user emotions and helps systems respond appropriately to satisfied or frustrated customers.

Dialog management

                                                                                                                                      Source

Dialog management links the voice AI components together. It controls voice AI conversations through two core processes:

1. Dialog modeling

The system records essential information to maintain the conversation state. It tracks discussed topics, stores user-provided details and identifies missing information needed to complete requests. This data is often structured into slots in a form populated with values gathered during the interaction. 

For example, in a hotel booking conversation, it tracks check-in dates, room preferences, and guest information until all required fields are complete.

2. Dialog control

The system determines the next action based on the collected information. It decides when to request missing details, verify unclear inputs, or proceed with task completion. Confidence scores guide these decisions; high scores lead to task execution, while low scores trigger clarification requests.

For example, if the check-in date is unclear when booking that hotel room, the system will ask for confirmation before proceeding.

Natural Language Generation (NLG)

The process converts system decisions into human-friendly responses. It begins when NLG receives input from the dialog management system. This input contains the intent and relevant information needed for the response.

The system then structures this data into a logical sequence and applies grammar rules specific to each language.

For example, when recommending a product, the system converts structured data like: recommend(product="Premium Plan", features="24/7 support, unlimited calls") to natural responses: "Would you like to try our Premium Plan with 24/7 support and unlimited calls?"

Text-to-speech Synthesis (TTS)

Text-to-speech technology converts written text into spoken words. It follows these steps:

• The process starts with text analysis, where the system breaks text into processable units.

• Next, it converts these units into phonetic symbols that represent speech sounds.
• The system then adds prosody — the patterns of rhythm and sound in speech. This includes marking where to pause, which words need emphasis, and how to adjust tone.
• Finally, deep learning models generate audio waveforms that produce the actual speech output.

Modern TTS systems support different languages and voices and process thousands of requests simultaneously.Putting it all together: The voice AI workflowVoice AI creates a continuous cycle of speech processing and response generation. Here's how the components connect:

1. ASR captures user speech and converts it to text. When a customer asks, "What's my account balance?" ASR processes the audio and produces text output.
2. NLP analyzes this text to identify the user's intent — for example, checking account balance. It gathers key details like account references and command types.
3. The dialog manager takes this processed request and checks if it has all needed information, retrieves the account balance from the connected system, and decides how to present this information to the user.
4. NLG formats the response and turns raw data like "balance: $1,245.50" into a clear statement: "Your current balance is $1,245.50."
5. TTS converts this text response into spoken words delivered to the user through speakers or phone lines.

Plivo's Voice API lets you add call functionality across devices through server-side software development kits (SDKs) in multiple programming languages. You can create interactive voice response (IVR) menus with speech recognition, set up real-time coaching for agents, and detect answering machines for smart responses.The platform processes voice interactions in 28 accents across many languages and supports dual-channel call recording with encryption. Debug logs monitor performance, while webhooks keep you updated on on-call status.

Managing large-scale conversations can be a challenge—especially for growing businesses.

To meet this demand, Meta launched the WhatsApp Cloud API in May 2022. This API lets businesses quickly connect with customers, offering a secure and scalable way to chat — no matter where they are.

While the Cloud API is easy to set up with no hosting fees, it does limit customization and control.

That’s where Plivo’s WhatsApp Business API comes in. Plivo offers more flexibility and control during setup, which can be beneficial for businesses in need of a more tailored solution.

In this guide, we’ll cover everything from setting up the Cloud API to real-world use cases, and also explore how Plivo’s API can offer more customization for businesses that need it.

WhatsApp Cloud API 101

Before launching the WhatsApp Cloud API, Meta offered three versions of WhatsApp:

• The standard WhatsApp app for personal use.
• WhatsApp Business for small- to mid-sized businesses.
• WhatsApp Business API for companies that needed advanced features.

So, what makes WhatsApp Cloud API different from all of these versions?

Let’s learn more about it.

What is WhatsApp Cloud API?

The WhatsApp Cloud API is a version of the WhatsApp Business Platform that runs on Meta’s cloud servers.

Unlike the older version, which required hosting on private servers or through a business solutions provider (BSP), the Cloud API removed the need for businesses to manage their own servers.

Why did Meta create the Cloud API?

The older on-premises API had its drawbacks. Set up took time, updates were slow to reach businesses, and server maintenance was expensive.

How does WhatsApp Cloud API work?

Here’s how the WhatsApp Cloud API works:

• Cloud-based architecture: Hosted on Meta’s servers, it provides a reliable and scalable infrastructure for messaging.
• Messaging capabilities: Businesses can exchange text, images, videos, and documents programmatically using API endpoints.
• Automation and bots: It supports automated workflows, such as sending appointment reminders or responding to frequently asked questions.
• Integration-friendly: The API connects seamlessly with other tools, streamlining customer communication processes.
• Multi-agent support: Teams can manage conversations collectively, ensuring faster response times and better customer service.

What’s the difference between the WhatsApp on-premises API and Whatsapp Cloud API?

Understanding the differences between the WhatsApp on-premises API and the WhatsApp Cloud API is key to choosing the right solution for your business.

Let’s explore how they compare.

WhatsApp business Cloud API features

The WhatsApp Cloud API comes with features that allow businesses to easily connect WhatsApp with their existing tools and workflows.

Here are its main offerings:

Seamless integration with Meta

Businesses can connect their systems to WhatsApp through Meta’s cloud platform. This ensures smooth and dependable communication with customers.

Versatile messaging options

The WhatsApp Cloud API supports text, media such as images, videos, audio, GIFs, and files, as well as contact cards and location sharing. It also facilitates interactive messages like list messages, reply buttons, and single or multi-product messages.

Additionally, businesses can use message templates for both text and media, incorporating interactive options for customer engagement.

Data access across platforms

The Graph API allows businesses to access and send data easily across different Meta platforms, including WhatsApp, Facebook, and Instagram.

It uses a single point of connection, so businesses don’t need to connect separately to each platform. This makes it simpler for businesses to manage data, whether it's about users, posts, or events, all from one place.

Global accessibility with no setup fees

The WhatsApp Cloud API is hosted in North America, but it allows businesses worldwide to connect with customers. This gives them access to WhatsApp’s large user base.

Meta offers the Cloud API for free, so businesses don't have to pay setup or access costs. However, businesses will still pay for the messages they send.

Easy-to-use API documentation

Meta offers straightforward API documentation, making it easier for developers to connect their systems to WhatsApp. This helps businesses build customized solutions and drive innovation.

Scalable and secure communication

The WhatsApp Cloud API enables businesses to scale their communications as they grow. It meets Meta’s strict security and privacy standards, ensuring both business and customer conversations remain secure.

How to get WhatsApp Cloud API

Setting up the WhatsApp Cloud API can vary depending on the method you choose. Here’s a quick comparison between using a BSP like Plivo and going through Meta directly.

Using an embedded signup

Signing up through a BSP enables you to complete the process in just a few steps. The signup flow is simple and stays entirely within the site.

Here’s how to do it with Plivo:

Step 1: Create a WABA in the Plivo console

To set up your WABA in Plivo, register a phone number that can receive an OTP via text or call. You'll use this number to message customers on WhatsApp.

You can either rent a number from Plivo or use your own. If you’re moving from another provider, you can transfer your number to Plivo.

Be sure to check Meta's guidelines and Plivo’s requirements for registration and migration.

Step 2: Customize your WhatsApp profile

Pick a display name for your WhatsApp account and follow the setup guidelines. Then, grant Plivo the necessary permissions to act as your WhatsApp solution provider.

Step 3: Verify successful onboarding

To confirm your setup is successful, check your Meta Business Account. First, choose your Meta account, then go to Business Settings and click on WhatsApp Accounts.

In the Partners tab, Plivo should appear as your partner.

Then, go to the Settings tab, where you'll find 'PLIVO INC' listed as a payment option.

Once you open "WhatsApp Manager," your number should show as connected.

Step 4: Register WhatsApp templates

Businesses must use WhatsApp messages templates approved by Meta. You can create new templates in WhatsApp Manager.

Meta segments templates into utility, marketing, or authentication categories, based on the message content. The category impacts both the conversation type and the cost.

In the Plivo console, you can find template information. Navigate to Messaging > WhatsApp Business Account > Templates to sync and view details from Meta.

Step 5: Manage your business phone number

Go to WhatsApp > WhatsApp Business Account to manage business phone numbers in Plivo.

Select your account and click on 'Configurations.' To add a phone number, use the ‘+Add Phone Number’ button found under account details.

After adding, you can also unlink numbers if needed.

This section also shows the connection status (whether it’s connected, pending, or disconnected), the name status (which reflects Meta’s verification), and the quality rating, based on how recipients respond to your messages.

Using Meta

Using the Cloud API through Meta requires development skills, such as making API calls to send and receive messages and setting up a webhook endpoint to handle message notifications.

You’ll also need to switch between Meta for Developers, your webhook server (like Glitch), and the WhatsApp application to test everything.

To learn more about these steps, refer to Meta’s documentation.

Note: Meta prohibits independent software vendors from developing the WhatsApp Cloud API for clients. Non-compliance with WhatsApp's Commerce Policy may lead to suspension or removal of API access.

WhatsApp Cloud API pricing

Businesses can access the WhatsApp Cloud API for free, but they pay based on their conversations with users.

Conversations on the WhatsApp Cloud API fall into two categories: user-initiated and business-initiated. A user-initiated conversation occurs when a user sends a message to a business, and the business responds within 24 hours. 

On the other hand, a business-initiated conversation happens when the business messages a user after the 24-hour window following the user's initial message.

WhatsApp offers the first 1,000 conversations each month for free. Once businesses exceed this limit, they must add a credit card to their account to continue using the service.

Even if a WABA has multiple phone numbers, the 1,000 free conversation limit still applies, and it resets monthly. In addition, businesses won’t incur charges when users contact them through the business’s call to action (CTA) button.

Pros of using the Whatsapp Cloud API

The WhatsApp Cloud API offers several advantages for businesses looking to integrate WhatsApp messaging into their customer service and communication workflows.

These advantages include:

Faster approval process

Previously, businesses had to go through BSPs and wait for approval before gaining access to the WhatsApp Business API. With the new approach, businesses can now directly access the API, removing the middleman.

Instant updates

Direct access to the WhatsApp Business API ensures that businesses immediately receive updates, including important security fixes.

Reduced costs

Traditionally, BSPs charged businesses for API access.

Now, with the WhatsApp Cloud API, Meta has eliminated setup charges, meaning businesses of all sizes can use the API at no cost.

Cons of using the Whatsapp Cloud API

While the WhatsApp Cloud API offers many benefits, there are also some potential drawbacks to consider:

Customization and control

The WhatsApp Cloud API is a ready-to-use solution managed by Meta. It makes setup and maintenance easy, but businesses can’t change its main features or underlying infrastructure. However, it allows for flexible integrations and workflow setups within its standard limits. For companies with complex needs or very specific requirements, this lack of control might be a drawback compared to on-premises options.

Support and service level agreement (SLAs)

Meta’s Cloud API support is general, whereas the on-premises API often includes specific SLAs and disaster recovery managed by BSPs. Businesses with high-stakes communication needs may find it challenging to operate without dedicated support. Downtimes or delays in issue resolution can impact critical service levels.

Plivo offers strong support with clear SLAs and disaster recovery measures. This dedicated service helps businesses maintain consistent, reliable communication when it matters most.

Feature parity and updates

The Cloud API may lack certain advanced features or update flexibility found in the on-premises API. Businesses using the Cloud API can face restrictions in accessing new tools or controlling update timing, limiting how they manage feature rollouts.

Plivo gives businesses more options, with multiple engagement channels like SMS, WhatsApp, and voice. Its additional features, such as marketing automation, provide flexibility beyond what the Cloud API offers.

For instance, Plivo allows businesses to provide customer support via a no-code AI-powered WhatsApp chatbot. This bot can handle routine customer inquiries, such as order tracking or store hours, without needing an agent. It reduces the workload on human agents and improves response speed.

Plivo also offers data-led routing, which uses customer data to direct queries to the right agents.

For example, if a returning customer has a technical issue, the system can route their inquiry to a dedicated technical support agent. This ensures the customer gets the right help faster and more efficiently.

Latency and performance

Meta’s North American data hosting can cause delays for international users, as requests must travel across continents. For global businesses, this lag can impact response times, making interactions feel slow and lowering user satisfaction.

Plivo’s network, with connectivity in over 220 countries and territories, routes requests closer to users to reduce latency. This setup helps businesses offer faster, more responsive service worldwide.

Automate your WhatsApp communication with Plivo

The WhatsApp Cloud API is fully managed by Meta, making it easier to set up and scale, but it gives you less control over infrastructure.

If you want something quick and easy, go for the Cloud API. If you need more customization and control, the Business API is the way to go.

Plivo offers a reliable and easy-to-use API platform that consolidates all your communication channels under one bill, contract, and point of contact. With competitive pricing and customer support ranked 99/100 for satisfaction on G2, you can count on us for top-tier service.

Plivo’s WhatsApp Business API makes managing customer interactions at scale effortless. Rich messaging and advanced automation tools not only improve customer satisfaction but also make your communication processes more efficient.

Voice Artificial Intelligence (AI) is no longer just a futuristic concept — it’s here, reshaping how businesses engage with customers. With the conversational AI market set to jump from $13.2 billion in 2024 to $49.9 billion by 2030, voice integration is transforming industries.

From handling customer queries to automating workflows, voice AI redefines e-commerce, healthcare, finance, and many industries. It’s not just about commands anymore; voice AI now delivers context-aware, natural interactions that transform customer experiences with real-time assistance and a sense of personal touch.

In this article, we’ll discuss how voice integration in conversational AI drives change, its industry applications, and the advantages it offers for businesses and customers.

What is conversational voice AI?

Conversational voice AI focuses on voice-based interactions between users and machines under the umbrella of conversational AI. It uses speech recognition and natural language processing (NLP) to understand and respond to voice commands. Speech recognition converts spoken words into text, while NLP uses algorithms to understand the intent of the converted text.

The response then reverts to speech through speech synthesis.

Various devices, such as smart speakers, mobile apps, interactive voice response (IVR) systems, and even in-car voice systems, use conversational voice AI to improve user engagement and operational efficiency.

Sneak peek of conversational AI: The OG

Conversational AI comprises technologies and algorithms that create lifelike conversations between machines and users. Users interact with these technologies via:

• Customer support chatbots found in apps or on websites
• Smart assistants like Google Assistant or Amazon Alexa
• Customer support voice bots that handle queries over the phone

Conversational AI systems process voice commands, understand user queries, and provide relevant responses using NLP, machine learning (ML), and speech recognition.

The rise of voice technology in conversational AI

🗣️: Ok Google, navigate to the closest gas station.

🗣️: Hi Siri, remind me to pick up groceries at 10 AM.

🗣️: Alexa, set a timer for 5 mins.

Google, Amazon, and Apple have transformed voice-based interactions using conversational AI.

Voice integration in conversational AI provides a natural and intuitive way to interact compared to traditional text-based methods. It mirrors human conversation, making it faster and easier for users to communicate with AI systems.

With 97% of mobile users relying on AI voice assistants, voice-based conversational AI is now a regular part of daily life. Businesses are adopting voice AI to offer seamless, hands-free experiences as consumers grow familiar with voice commands.

Looking under the hood: Conversational voice AI and customer service

Conversational AI in customer service helps businesses offer instant support to customers and handle routine tasks with ease. Voice-enabled conversational AI answers queries, processes requests, and speeds up customer interactions. This improves efficiency, reduces wait times, and lets agents focus on complex issues.

Let’s explore the different applications of conversational AI that can amp up the game of customer experiences across the board.

Smart call routing

Voice assistants with conversational AI analyze customer inquiries and route calls to the right department.

Unlike traditional IVR systems that rely on keywords, voice AI maximizes IVR menu efficiency through natural language understanding (NLU), allowing customers to speak naturally.

Voice assistants also capture customer details, like names, account numbers, and requested services, giving agents all information upfront. This saves time for both customers and agents.

Omnichannel support

While text, email, and chat are standard communication channels, voice adds immediacy and a personal touch to customer service interactions, which other channels often lack.

With voice AI in their omnichannel support system, businesses can offer seamless platform transitions. For instance, a customer might use voice commands in-store to check product availability and continue the conversation online later.

This unified experience provides a smooth customer journey and boosts customer satisfaction and brand loyalty.

Pro Tip: Add customizable voice IVR to your omnichannel support and build a better brand perception.

Streamline authentication

Automating customer authentication with voice technology and conversational AI reduces time and costs. Additionally, voice authentication using NLP is a more cost-effective alternative to voice biometrics authentication, providing an equally smooth experience.

Simplify troubleshooting

Voice assistants powered by conversational AI and chatbots can handle much of the troubleshooting process, automating common issues and often resolving them without involving an agent. This reduces agents' time on repetitive tasks and boosts customer service operations.

If the bot can’t resolve the issue, it transfers the customer to a human agent. It also gives the agent a detailed record of already taken troubleshooting steps to ensure a smoother handoff.

More agent efficiency = Better customer experience.

Better security and reliability

In industries like finance and healthcare, security is paramount.

Voice AI integration provides robust security measures, such as encrypted voice recordings and secure data transmission. It protects sensitive customer data while meeting industry regulations.

A dependable voice platform with voice AI reduces downtime and ensures continuous service through a well-designed IVR system. For example, banking IVRs improve security and customer interactions and ensure a smooth, secure flow of information.

Multi-language support

Voice technology with conversational AI allows businesses to support multiple languages and create a more inclusive and accessible customer experience. For example, Plivo’s AI voice agents support speech recognition in 27 languages and their regional variants.

Using speech recognition technology, businesses can engage with diverse customer bases worldwide and offer personalized support in various languages. It helps companies enhance customer interactions and improve overall satisfaction.

Hands-free experience

98% of websites don’t provide basic accessibility features, limiting access to millions of users with disabilities. Voice-enabled conversational AI supports Web Content Accessibility Guidelines (WCAG) and allows more customers to access digital services independently.

Voice technology powered by conversational AI uses advanced speech synthesis to support users with visual impairments. It enables interaction with content through natural-sounding speech, making information easier to understand and more engaging.

These systems convert text into audio, providing access to online shopping, education, and training in a more inclusive way.

Personalization

Conversational AI platforms leverage customer data like browsing history and purchase behavior to offer highly personalized recommendations in real-time. For example, voice assistants can narrow down a general query about a mobile phone to a specific model based on the customer's preferences and budget.

Voice-enabled AI bots, like Plivo-powered voice agents, also guide customers from discovery to checkout, helping them:

• Compare products
• Suggest complementary items
• Offer specific discounts
• Upsell based on past purchases

Unlike text-based bots, voice agents are more personalized, adding a human touch to customer interactions.

Conversational voice AI for different industries

When a customer calls, they want to feel valued and understood. Conversational AI with voice recognition technology puts the customer at the center of the experience.

Here’s how voice AI transforms industries and enhances customer interactions across sectors.

E-commerce

E-commerce customers want quick responses and 24/7 support. If they don’t get it, they may choose a competitor.

While chatbots work well for tasks like answering FAQs or checking order status, voice integration in conversational AI transforms customer service and creates standout shopping experiences by:

• Assisting customers with product selection
• Offering personalized recommendations
• Automating the sales process

Integrating voice agents in customer relationship management (CRM) systems also provides real-time updates, such as order status, with just a voice command. Businesses are better suited to provide a 24/7 personalized shopping experience with quicker response times and higher customer engagement.

Education

AI voice integration with multilingual support can empower inclusive learning experiences in the education sector with personalized tutoring. Voice agents can instantly support students by providing real-time translations and remove language barriers by clarifying complex terms in their preferred language.

This integration reduces the need for multilingual staff, making learning more accessible for global students.

No industry values prompt responses more than healthcare.

Voice integration in conversational AI healthcare sectors improves customer experience, provides timely care, and improves operational efficiency. It simplifies patient care and delivers personalized support through:

• Medication reminders 
• Appointment scheduling
• Preliminary health assessments

In addition, voice agents help healthcare providers automate tasks, improve medication adherence, and lighten their workload, making services more efficient and patient-focused.

Finance

Conversational voice AI supports financial sectors with a forward-thinking approach. Voice agents improve the customer experience by offering quick, accurate responses without wait times. Banks use voice agents to:

• Automate routine tasks
• Provide instant account updates

Approaches to deploying conversational AI for voice integration

When you're ready to implement voice-integrated conversational AI, you'll discover several ways to design, build, and deploy a voice assistant. Some approaches may appear cost-effective at first but quickly turn into obstacles, complicating deployment or causing user dissatisfaction.

Here are three primary methods for deploying conversational AI for voice:

1. Partner with a voice-first vendor

Partnering with a voice-first vendor like Plivo is the most efficient and effective way to deploy conversational AI for voice applications.

One of the key advantages of working with a vendor like Plivo is the speed and efficiency it brings to deployment. Instead of building a voice assistant from the ground up, businesses can leverage Plivo’s pre-built solutions and technical expertise. This accelerates time-to-market and reduces the burden on in-house development teams.

Plivo's platform is designed to handle the complexities of voice integration, such as managing call flows, ensuring compliance with global telecommunication standards, and delivering high-quality audio. Additionally, its APIs are highly customizable, allowing businesses to tailor their solutions to fit specific use cases.

2. DIY with a third-party platform

Another approach to deploying conversational AI for voice is using third-party platforms like Google DialogFlow or Amazon Lex. They can handle natural language processing and speech algorithms for your applications.

However, this option may limit control. Performance can vary based on language or application needs, especially in voice-heavy use cases.

3. Port chatbot technology into voice

Many businesses start with chatbots and attempt to convert them into voicebots.

Doing so involves integrating speech recognition and text-to-speech capabilities with the chatbot’s existing NLP engine. This allows the system to understand spoken input, process it, and deliver relevant responses through audio.

Nevertheless, transitioning from a text-based chatbot to a conversational AI voice agent can be challenging.

Chatbots are primarily designed for text-based communication, and the conversion process often leads to issues with speech recognition and intent detection, resulting in subpar performance. It also requires careful attention to voice-specific nuances, such as accommodating variations in accents, ensuring accurate speech synthesis, and optimizing dialogue flow for spoken interactions.

Note: While porting chatbot technology to voice can save time and resources compared to building a voice assistant from the ground up, it may lack the full customization and voice-centric features provided by dedicated voice-first solutions.
