In the interconnected world of apps, websites, and digital services, ensuring secure user access is more critical than ever. That’s where authentication and authorization come into play. These two terms often appear side-by-side in conversations about cybersecurity and user access, but they’re far from interchangeable.

Think of authentication as verifying your identity at the door, and authorization as the VIP list determining what areas you can access once inside. Both are essential for keeping digital spaces secure, but their roles are distinct—and understanding the difference is key to building safer systems and more seamless user experiences.

In this blog, we’ll break down the fundamentals of authentication and authorization, explore how they work together, and examine why they matter for individuals and organizations alike.

How does authentication verify user identity?

Authentication is the cornerstone of digital security, tasked with verifying that a user or entity is genuinely who they claim to be. Without authentication, systems cannot differentiate between legitimate users and malicious actors attempting unauthorized access.

At its core, authentication involves a user providing credentials—such as a username and password—that are compared against stored data. If the credentials match, the system permits access. However, traditional methods like passwords have vulnerabilities, prompting the adoption of more advanced techniques.

What are the common types of authentication methods?

Authentication mechanisms can be classified into three main categories based on the type of credentials required:

1. Something you know: Includes passwords, PINs, and answers to security questions. These methods rely on the assumption that only the authorized user knows the required information.
2. Something you have: Examples include physical devices like security tokens, mobile phones for OTP delivery, or smart cards. These add an extra layer of security by requiring possession of an item.
3. Something you are: Biometric authentication leverages unique physical attributes like fingerprints, iris scans, or facial recognition, making it one of the most secure forms of identity verification.

Combining these methods through multi-factor authentication (MFA) strengthens security by requiring two or more forms of verification.

Why is multi-factor authentication (MFA) critical?

While traditional authentication methods offer a basic level of security, they can be vulnerable to attacks such as phishing or credential theft. This is where multi-factor authentication (MFA) comes in—by requiring two or more verification methods, MFA significantly reduces the risk of unauthorized access. For instance, a banking application might require both a password (something you know) and an OTP sent to your mobile device (something you have) before granting access.

MFA mitigates common vulnerabilities of single-factor authentication by making it harder for attackers to breach systems, even if one credential is compromised. It is particularly important for high-security environments such as financial institutions or cloud services.

How does authentication operate in cloud environments?

With businesses rapidly shifting to cloud-based platforms, authentication must evolve to meet the challenges of remote access and global connectivity. Cloud computing, with its shared infrastructure and global accessibility, demands robust authentication mechanisms. Traditional username-password combinations are often insufficient, so advanced approaches like token-based authentication and Single Sign-On (SSO) are widely used. These methods simplify access for users while maintaining strict security standards.

For example, SSO enables users to authenticate once and access multiple applications seamlessly. Coupled with standards like OAuth 2.0 and OpenID Connect, SSO ensures both security and convenience, making it an integral part of modern authentication in cloud environments.

How do authentication and authorization work together?

Authentication and authorization are integral processes that work in sequence to protect systems and data. Authentication identifies who the user is, while authorization determines their permissions within the system. Together, they ensure that only verified users gain access to the resources they are allowed to use, forming a robust framework for digital security.

Why must authentication always precede authorization?

Authentication and authorization are sequential processes that work in tandem to secure systems and data. Authentication verifies a user’s identity, forming the foundation for authorization to define what the user can do within the system. Without authentication, a system cannot determine whether a user is legitimate, making it impossible to assign permissions accurately.

For example, consider an enterprise resource management system. Authentication ensures a user, such as a department manager, is genuinely who they claim to be. Once authenticated, authorization evaluates their role and grants access to department-specific data while restricting other sensitive areas, such as payroll records for other departments.

What protocols effectively integrate authentication and authorization?

1. OpenID Connect (OIDC)
   OIDC, built on OAuth 2.0, focuses on user authentication by verifying identity and providing ID tokens to applications. It is particularly useful in Single Sign-On (SSO) environments, enabling users to authenticate once and access multiple applications seamlessly.
2. OAuth 2.0
   OAuth 2.0 primarily handles authorization. It issues access tokens that grant limited permissions to third-party applications. For instance, a user can authorize a travel app to access their calendar to book flights without sharing their login credentials.

Together, OIDC and OAuth 2.0 provide a cohesive framework for managing authentication and authorization, ensuring secure and streamlined access control.

How do authentication and authorization complement each other in IAM systems?

Identity and Access Management (IAM) systems rely on the synergy between authentication and authorization to provide comprehensive security. While authentication confirms a user’s identity, authorization enforces granular access controls based on predefined policies.

For example:

• A marketing analyst authenticates into a shared cloud platform.
• Authorization allows access to customer analytics dashboards but restricts access to sensitive financial data meant for the finance team.

This integration not only enhances security but also improves the user experience by ensuring users can seamlessly access the resources they need without encountering unnecessary barriers.

What are the strengths and weaknesses of traditional authentication methods?

Traditional authentication methods often rely on verifying something a user knows, such as a password or PIN. While straightforward and familiar, these methods have inherent weaknesses:

1. Password-based authentication:
   
   • Strengths: Universally understood and simple to implement.
   • Weaknesses: Susceptible to phishing, brute-force attacks, and credential stuffing. Users often reuse or create weak passwords, making them a common attack vector.
2. Knowledge-based authentication (KBA):
   
   • Strengths: Uses answers to security questions, adding an extra layer of protection.
   • Weaknesses: Answers can often be guessed or researched, especially when questions rely on personal information.

These methods, while widely used, require additional safeguards to address their vulnerabilities.

How do biometric and possession-based methods enhance authentication?

Authentication methods based on something a user has or is, provide a higher level of security:

1. Possession-based authentication:
   Examples include physical devices like smart cards, security tokens, or mobile phones used to receive one-time passwords (OTPs).
   
   • Strengths: Tied directly to the user's possession, making them harder to replicate.
   • Weaknesses: Devices can be lost or stolen, potentially compromising security.
2. Biometric authentication:
   Employs unique physical traits like fingerprints, retina scans, or voice recognition.
   
   • Strengths: Difficult to forge and highly reliable when implemented correctly.
   • Weaknesses: Biometric data, if compromised, cannot be replaced, raising significant privacy concerns.

These methods often form the foundation of multi-factor authentication (MFA) systems, combining possession or biometric factors with traditional credentials to mitigate risks.

What are adaptive and passwordless authentication techniques?

Advanced authentication techniques are emerging to address the evolving threat landscape and user demands for convenience:

1. Adaptive authentication:
   Uses machine learning and context-aware policies to evaluate risk factors, such as location, device, or login time.
   
   • Example: A system might prompt for additional verification if a user logs in from an unusual location.
   • Strengths: Dynamically adjusts security measures based on risk, improving both security and usability.
2. Passwordless authentication:
   Eliminates the reliance on traditional passwords, using methods like biometrics, hardware tokens, or magic links sent to a user’s email.
   
   • Strengths: Reduces phishing risks and enhances user convenience.
   • Weaknesses: Requires advanced infrastructure and user education for widespread adoption.

These approaches represent the future of secure and user-friendly authentication systems.

What are the key differences and similarities between authentication and authorization?

Authentication and authorization serve distinct purposes in access control systems:

• Authentication: Focuses on verifying identity. It answers the question, "Who are you?" and allows only legitimate users to log in. Examples include passwords, biometric scans, or OTPs.
• Authorization: Determines what a user is allowed to do after they’ve been authenticated. It answers, "What are you allowed to access?" For instance, an authenticated user might be able to view files but not edit them.

The main distinction lies in their roles: authentication validates identity, while authorization defines permissions.

How do tokens facilitate both processes?

In modern access control systems, tokens play a critical role in separating authentication and authorization:

1. ID Tokens:
   
   • Issued during authentication to confirm a user’s identity.
   • Typically contains user details such as name, email, and login time.
   • Example: OpenID Connect generates ID tokens after a user logs in.
2. Access Tokens:
   
   • Issued during authorization to define the permissions granted to the user or application.
   • Allow a user to interact with specific resources (e.g., files, APIs) without revealing sensitive credentials.
   • Example: OAuth 2.0 uses access tokens to permit third-party apps to access user data within predefined limits.

By segregating authentication (ID tokens) and authorization (access tokens), systems maintain both security and clarity in managing access.

How do authentication and authorization complement each other?

Authentication and authorization are complementary processes, working together to provide robust access control:

1. Authentication establishes trust: Ensures that only legitimate users enter the system.
2. Authorization enforces boundaries: Restricts user actions based on predefined policies.

For example, in a corporate email system:

• Authentication verifies an employee’s identity via a company-issued login.
• Authorization determines whether the employee can access confidential documents or edit shared files.

Together, these processes create a multi-layered security approach, minimizing risks like unauthorized access and data breaches.

Why are both authentication and authorization critical for complete security?

Neither authentication nor authorization can independently secure a system. Relying solely on authentication might let verified users access sensitive areas they’re not permitted to view, while exclusive reliance on authorization without authentication would grant access without ensuring the user is legitimate.

For example:

• A cloud storage system might authenticate a user with valid credentials but use authorization to restrict access to sensitive financial reports, ensuring that only authorized roles, such as CFOs, can view them.

This synergy is particularly vital in regulatory compliance environments like HIPAA, where access to sensitive information is strictly governed.

Overview of SMS 2FA

SMS 2FA (two-factor authentication) adds a critical layer of security to online accounts. When users log into a website, software, or application, they receive a one-time numeric code via text message. This code acts as a second step in the authentication process, ensuring only the individual with access to the linked phone number can proceed.

For businesses in retail, healthcare, and fintech, SMS 2FA is a popular choice to safeguard sensitive customer data and prevent unauthorized access. By requiring something users know (a password) and something they have (a mobile phone), it significantly reduces the risk of data breaches.

While SMS 2FA is simple to implement and user-friendly, its security depends on how well it addresses threats like phishing and SIM swapping. As decision-makers, you need to weigh its ease of use against the level of protection it offers your business and customers.

So, why did businesses initially gravitate towards SMS 2FA? Let's examine the factors that made it a preferred choice in the early days.

Let's now walk through the steps involved in a typical SMS authentication process.

How does SMS authentication work?

SMS authentication offers a simple way to enhance security while keeping the user experience intuitive. Here’s how it works:

1. User logs in:

A customer visits your website and enters their username and password to log in. They trust your platform with their personal information and expect a smooth, secure experience.

2. One-time password (OTP) sent:

Immediately, your system triggers an SMS with a unique one-time password (OTP) sent to the customer’s registered phone number. This step adds an extra layer of security beyond just their password.

3. User inputs OTP:

The customer receives the OTP on their mobile device and enters it into the login screen. This ensures the person trying to access the account is the legitimate user, as only they would have access to the phone where the OTP was sent.

4. Access granted:

If the OTP matches, your system verifies the user’s identity and grants them access to their account. With SMS authentication in place, your business reduces the risk of unauthorized access, enhancing both security and customer trust.

This approach to SMS authentication strengthens security, reassures customers about their data, and keeps the login process simple and user-friendly.

Timing and frequency

Send messages during optimal times—typically within business hours or late afternoons—when recipients are more likely to engage. Avoid sending messages too early in the morning or too late at night, as this can annoy customers.

Frequency is equally important. Sending messages too frequently can overwhelm your audience, while too few messages may lead to missed opportunities. A good guideline is to send no more than 1-2 promotional messages per week.

Obtaining consent: why opt-in is crucial

Before sending any promotional messages, always obtain explicit consent from your customers to ensure compliance with regulations like the Telephone Consumer Protection Act (TCPA) and GDPR. Opt-in permissions also help build trust with your audience. Use clear opt-in messages, such as "Sign up for exclusive offers via SMS," and always provide an easy way to opt-out, like "Reply STOP to unsubscribe."

Crafting a clear call-to-action (CTA)

Each promotional message should feature a direct, clear CTA. Whether it’s “Shop now,” “Claim your discount,” or “Visit our store,” ensure that the CTA is straightforward and easy for the recipient to act upon.

Tracking the effectiveness of SMS campaigns

Tracking key metrics such as open rates, click-through rates (CTR), and conversion rates is essential to evaluate the success of your SMS campaigns. By monitoring these metrics, you can identify what’s working, make necessary adjustments, and optimize your future campaigns for better results.

Legal considerations

When using SMS for promotional campaigns, businesses must ensure they are compliant with various laws and regulations designed to protect consumers from unwanted marketing and data misuse. These regulations govern the use of SMS as a marketing tool and are in place to prevent abuse, such as spamming customers with unsolicited messages. Non-compliance can result in heavy fines, legal repercussions, and damage to your brand’s reputation.

Multi-Factor Authentication (MFA) is an essential safeguard for protecting sensitive information. However, as crucial as it is for security, the MFA recovery process can sometimes be a double-edged sword. If users lose access to their authentication method, they risk being locked out of their accounts. Therefore, a robust MFA recovery process should be a critical part of any authentication strategy.

Let’s walk through best practices for MFA account recovery to ensure your users can easily and securely regain access to their accounts.

Authentication requirements for account recovery

While traditional MFA methods provide excellent security, the MFA recovery process requires a slightly different approach. Recovery methods must be easily accessible, and memorable, and allow for a slower authentication process. Recovering an account isn't something most users would be required to do regularly.

The key requirements for a recovery system are:

1. Long-term memorability or access: Users need to easily retrieve their recovery method, even if they don’t use it regularly.
2. A slower authentication process is acceptable: Since account recovery is infrequent, a slight delay in authentication is fine as long as security is not compromised.
3. Widely usable: The recovery method must be accessible and practical for most users across different devices and locations.

The right balance is essential. Your recovery process should be secure enough to prevent unauthorized access but user-friendly enough to prevent frustration. 

Plivo’s Verify API, which supports multiple channels like SMS and in-app push notifications, can be an excellent tool for ensuring users have quick, secure access to their recovery methods.

What are the options for account recovery?

Gone are the days of relying on security questions for account recovery. The National Institute of Standards and Technology (NIST) has since recommended shifting away from these outdated methods due to their vulnerability. Today, the most reliable account recovery options involve using possession-based methods or account activity details.

1. Possession methods

Possession-based recovery methods are more secure than knowledge-based methods like security questions. Examples include:

• Backup codes: These are typically one-time-use codes that can be generated during the initial MFA setup. Users should store these codes securely in case of device loss or other issues. While they may seem simple, they offer a solid layer of security.
• Passkeys: A passwordless option that syncs private keys across devices, making it easier for users to recover their accounts without needing to remember complex passwords. Although passkeys are still being adopted, they offer a promising solution for both MFA and recovery.

Implementing these methods provides a secure fallback when users lose access to their primary authentication methods. Plivo’s Verify API can easily integrate into your system to deliver SMS-based recovery codes, offering both security and simplicity for users who need to regain access.

2. Account activity details

Another way to strengthen your recovery process is by leveraging account activity details. For example, asking users to confirm recent transactions or other identifiable actions can serve as a powerful recovery tool. These methods provide additional layers of security, helping to confirm a user's identity when primary credentials are unavailable.

How can social proof enhance account recovery processes?

Digital services and online platforms such as social networks or apps use trusted contacts or social proof to enhance their recovery processes. This could be a friend or family member who can verify the user’s identity. For example, platforms like Apple and Facebook use recovery contacts, allowing users to set up people who can help them regain access if needed.

However, this method works best for social networks with a large, established user base. If your service doesn’t have this feature built-in, focusing on other recovery options—such as backup codes and passkeys—can still provide strong security and ease of use.

How to strengthen your account recovery process?

To improve your account recovery process, consider the following recommendations:

1. Register additional authentication methods: Ensure that users register multiple recovery methods during account setup. This gives them options to access their account if they lose access to one method.
2. Design recovery processes based on data sensitivity: The higher the value of the data you're protecting, the more robust your recovery process should be. For sensitive services like financial applications, additional security layers are necessary.
3. Require successful MFA setup before new methods: Before enabling new MFA methods, ensure users have successfully completed the MFA setup process to avoid issues during recovery.
4. Prompt users about available recovery options: Regularly remind users of the backup methods available to them, particularly when logging in from new devices or after a password change.

Enhancing recovery process security

When enhancing your recovery process, keep these security measures in mind:

1. Implement waiting periods: For sensitive recoveries, a waiting period can act as a deterrent for unauthorized access attempts. This gives you time to review and confirm that the recovery request is legitimate.
2. Maintain MFA during recovery: Don’t deactivate MFA when users are trying to recover their accounts. This ensures that multiple authentication steps are still in place, preventing unauthorized access.

The MFA recovery process should always remain as secure as possible, even if it’s a bit slower than regular authentication. By adding layers of security, such as SMS or app-based MFA, you can ensure that both you and your users stay protected.

Effective SMS communication hinges on one key factor—ensuring messages are successfully delivered. 

However, not every text message reaches its destination. 

Various technical and regulatory factors can interfere with SMS transmission, preventing messages from being received.

For instance, in 2023, e-commerce brands worldwide sent 57.9% more SMS campaigns than the previous year, yet despite a solid 7.6% click rate and a modest 0.13% conversion rate, the overall increase in orders was only 9.4%. 

This underscores the impact that undelivered messages can have on campaign success. To tackle this, understanding the SMS delivery process helps businesses identify potential delivery roadblocks and refine their messaging strategy. 

In this article, we’ll explore how SMS delivery works, the different stages of message transmission, common reasons for failed deliveries, and strategies to maximize SMS reach and effectiveness.

How does SMS delivery work?

SMS delivery is the process of transmitting text messages from a sender to a recipient's mobile device. Understanding the distinctions between different stages of SMS delivery can help businesses optimize their communication strategies. 

‍

Here’s a breakdown of the key concepts and the SMS delivery process:

‍

SMS delivery process

Knowing how SMS is delivered can optimize your SMS campaigns. Here's a brief overview of how a message travels from initiation to delivery or potential blockage:

1. Message sent: The sender’s platform creates and sends the SMS.
2. Message routed: The SMS gateway receives the message and directs it to the appropriate mobile carrier. This step involves passing through various network gateways, and possibly different carriers if the sender and recipient are on different networks.‍
3. Carrier processing:

          👉 The carrier checks network availability and the recipient's status to determine if it can deliver the message.

           👉 If approved, the carrier delivers the message to the recipient’s device.

           👉 If flagged, the carrier filters or blocks the message, preventing delivery.

Key factors that impact SMS deliverability

Understanding what affects SMS deliverability is crucial for successful messaging. Here are the key factors that impact SMS deliverability:

1. Carrier filtering

Most mobile carriers actively prevent spam by filtering messages that show suspicious patterns. These filters analyze the sender's behavior, such as message frequency and the consistency of volume over time.

For example, a sudden spike in message volume from a new number may trigger carrier filters to block those messages, interpreting them as potential spam.

‍

2. Message content

The actual text of your messages can trigger spam filters if they contain certain keywords or phrases typically associated with spam. Messages that include phrases like "You've won!" or "Claim your prize now!" are more likely to be flagged as spam.

Additionally, messages that include shady links or that do not comply with formatting rules (like including non-standard characters) are more likely to be filtered.

‍

4. Network issues

Factors such as network reliability during high traffic periods or technical failures can hinder SMS delivery success beyond content and reputation. 

Similarly, if the recipient's phone is off, out of range, or has inbox storage issues, these problems must be resolved before the message can be delivered.

For example, during natural disasters, networks may become congested, leading to higher rates of undelivered messages.

‍

5. Regulatory compliance

Regulations around SMS messaging vary significantly by region and country with local and international laws. Most regions have Do Not Disturb (DND) lists and strict opt-in and opt-out rules that must be adhered to.

Regulations like the GDPR in Europe and the TCPA in the U.S. govern how businesses can collect, store, and use mobile numbers. Non-compliance can not only lead to blocked messages but also hefty fines.

For example, a U.S. company must have explicit consent from users before sending them marketing SMS and must provide an easy way to opt out of every message.

Understanding and addressing these factors will help businesses maintain high deliverability rates for their SMS campaigns, ensuring that messages reach their intended recipients efficiently and legally.

Common SMS delivery failure reasons & solutions

Proven best practices to maximize SMS delivery rates

Ensuring high SMS delivery rates is critical for effective communication. Here are proven best practices to maximize SMS deliverability.

1. Keep a clean contact list

Invalid or outdated numbers can lead to high bounce rates and lower overall deliverability. 

Example:

An online fashion store sends a flash sale SMS to 50,000 contacts but notices a 20% bounce rate. After auditing their contact list, they found that many numbers were outdated or mistyped. They introduce an SMS verification step at checkout, reducing their bounce rate and ensuring messages reach real customers.

Regularly clean your contact list by:

• Removing inactive or invalid numbers
• Using opt-in methods to ensure recipients want to receive your messages
• Updating contact information periodically to avoid sending messages to non-existent numbers

2. Optimize message formatting & structure

Poorly formatted SMS messages can be blocked by carriers or ignored by recipients. To improve deliverability, keep messages short, avoid excessive special characters, and make the CTA clear.

Example:
Poor formatting:

‍
"🔥 BIG SALE!! Click NOW 👉 bit.ly/abcd to get 50% OFF!! Limited Time! 🚀"

Better formatting:

‍
"Hey [Name], our biggest sale of the season is live! Get 50% off sitewide. Shop now: www.brand.com"

By using a branded link instead of a generic shortener, the e-commerce brand avoids carrier spam filters and increases trust.

3. Timing and frequency

The timing and frequency of your messages can affect both user engagement and deliverability. 

Schedule SMS to arrive during optimal times based on customer behavior patterns and avoid sending too many messages in a short period, which can lead to unsubscribes or spam complaints.

Example:

An electronics store adjusts their cart abandonment SMS reminders from 30 minutes to 4 hours after customers leave the site. After analyzing the results, this timing adjustment significantly boosts recovery rates, as customers are more responsive later

4. Customer segmentation

Not all recipients should receive the same message. Segmenting your audience allows for personalized and relevant communication. Consider:

• Segment contacts by demographics, purchase history, or engagement
• Send targeted messages based on preferences and past interactions
• Use dynamic content for personalized, high-response messages

Generic messages don’t work for e-commerce brands. Segmenting customers ensures that messages are relevant, leading to higher open and conversion rates.

Example:
A skincare brand segments its customers into three groups:

• New buyers receive a welcome SMS with a 10% discount on their next purchase
• Frequent shoppers get exclusive early access to sales
• Inactive customers receive a “We miss you” message with a special offer

5. Ensure compliance with local & global SMS laws

Adhering to SMS regulations is non-negotiable for legal operations and maintaining customer trust.

Familiarize yourself with local and international laws such as GDPR in Europe or TCPA in the U.S. Always get consent before sending SMS, provide clear opt-out options, and maintain records of these consents.

6. Monitor & analyze delivery reports

Continuous monitoring and analysis of your SMS campaigns’ performance help in understanding delivery success rates and identifying areas for improvement.

Key metrics to monitor include:

• Delivery rates to detect potential carrier or formatting issues
• Failure reports to understand common reasons for non-delivery
• Response times to measure engagement and campaign effectiveness

Example:

An online pet supply store finds that messages to specific regions are blocked, leading to high undelivery rates. After analyzing reports and adjusting sender IDs with their SMS provider, they significantly improve deliverability in those areas.

By implementing these best practices, businesses can ensure their SMS messages reach the right customers, improve engagement, and drive more sales.

Hiring customer service agents is expensive, no matter how you cut it. However, losing them is worse. 

A high customer service agent turnover means you have to put up with ever-ending cycles of recruitment costs, along with longer wait times for your customers. Also, such an environment often leads to more burned-out employees.

Overall, this can spell doom for your contact center, and by extension, your brand. 

On average, call centers face turnover rates between 30-45%. Gallup data suggests that replacing a single agent can cost up to 40% of their annual salary. 

But the hidden costs go way beyond recruitment and training. Lost productivity, declining service quality, and increased agent burnout—a cycle that’s difficult to break.

If turnover is draining your resources and hurting your customer experience, it’s time to act. This guide breaks down why agents leave, the actual cost of customer service agent turnover, and practical steps you can take to retain your team.

Understanding customer service agent turnover 

Employee turnover has shifted dramatically in recent years. It all began with the Great Resignation in 2021, which saw record-high quit rates (47.8 million) as workers sought better benefits and work-life balance. 

In 2025, turnover still is a big challenge. 

While turnover rates have declined from the 2021-2022 peak, they still remain significant. The latest data shows an average U.S. resignation rate of 17.3%, down from 24.7%. 

Despite this decline, workers face job dissatisfaction. In 2025, 56% of workers are looking for a new job. Additionally, Forbes predicts a similar scene to the Great Resignation in 2025 as employers are waiving off benefits and cutting salaries.

According to this Reddit thread, some of the major reasons employees are leaving  include: 

• Burnout and stress: Some users have described their job as “soul-sucking” due to the repetitive nature, demanding metrics, and constant pressure to perform.
• Poor management: Ineffective, uncaring, or power-tripping supervisors contribute to turnover. Other major issues include a lack of support from management and not feeling appreciated.
• Overemphasis on metrics: A relentless focus on speed and efficiency over customer experience leads to employee dissatisfaction and churn. Agents feel like they are treated as machines rather than human beings.
• Lack of career advancement: Limited opportunities for growth within the company can make agents feel stuck and unmotivated. The removal of career advancement resources was explicitly mentioned as a negative factor.
• Low pay and benefits: While some call centers offer decent pay and benefits, others do not. Employees are more likely to leave when compensation doesn’t match the job demands.
• Difficult work environment: Understaffing, constant policy changes, and having to handle multiple responsibilities (calls, back-office work, escalations) create a challenging and overwhelming environment.
• Lack of training and support: Inadequate training, especially in complex systems, leads to frustration and early departures. 
• Feeling like just a number: Agents often feel devalued and replaceable, leading to a disconnect and lack of loyalty.
• Better opportunities: Agents will leave for better-paying positions or opportunities in other fields, especially when they feel undervalued or burned out in their current roles.

Change in company culture: A shift in focus from customer experience to speed, stricter metrics, and reduced support can drive long-term employees to leave.Cost of customer service agent turnover 

Here are some financial and operational costs associated with high customer service agent turnover:

Financial costs

Recruitment and hiring expenses

These include all costs incurred to fill a newly vacant position, like expenses related to advertising, interviewing, and conducting background checks. 

‍

According to the Society for Human Resource Management (SHRM) research, the average cost per hire is nearly $4,700. These expenses could rise further if you include “soft costs,” such as time spent looking for candidates.

Training and onboarding costs

Average costs of onboarding an employee could be up to $1830. 

‍

This will also depend on a couple of factors including experience level, training needed, and ongoing support until they reach their full productivity. 

Separation costs

All costs related to the employee’s departure, including exit interviews, administrative tasks, and potential severance pay, are covered.

New agent productivity costs

All expenses incurred when onboarding and training a new agent until they can handle all customer interactions efficiently, including the cost of initial training, lost productivity during the learning process, and errors made during the onboarding period.

Employee lifetime value costs

ELTV is the total expected value of an employee's contributions to an organization during their employment period. 

‍

The longer the agents stay with your company, the higher the worth. When agents leave your organization, their knowledge and value leave with them, impacting your service level.

Customer satisfaction costs

When new agents are still training, they lack the in-depth product knowledge or skills to solve customer problems swiftly. This can disrupt customer service and lead to dissatisfaction.

Operational impact

Service disruptions and productivity loss

When agents leave, the remaining employees are under additional pressure to get work done. 

‍

Their absence can lead to frequent disruptions in workflow, and high work pressure can easily overwhelm and stress the employees, leading to decreased productivity.

Decline in customer service quality

New hires can take time to learn professional skills and speed up services. This can lead to long-drawn wait times, inconsistent service, and more escalations with unresolved issues. This results in more customer frustration.

Negative organizational culture

Frequent turnover can create uncertainty, making employees question job stability. Moreover, constantly disrupted relationships can weaken team cohesion and make employees feel undervalued and overworked.

How to reduce customer service agent turnover

Controlling agent turnover has long-term payoffs. Proactively solving its root causes leads to higher productivity, stronger agent engagement, and consistently better customer service. 

Here are some expert-recommended strategies to reduce customer service agent turnover:

Identify early warning signs

Agents don’t decide to leave overnight. There are a series of signs you need to watch out for to identify hints of abandonment:

• Decreased enthusiasm and engagement
• Rise in absenteeism
• Decline in performance with agents struggling to meet their targets or a drop in quality
• Negative interactions with customers or colleagues
• Increase in complaints expressing frustration or dissatisfaction with their workload or management

‍

If you notice any of these signs, communicate with your employees, understand their concerns and work on improving their experience.

Arrange flexible working conditions

 A US Career study indicated that in 2024, over 95% of workers desired some form of remote work. Specifically, 54% preferred to work fully remotely, 41% favored a hybrid schedule, and only 5% wished to work in the office full-time.

‍

Offering remote and hybrid arrangements can motivate employees to work better. All you need to do is support your employees with necessary AI-powered tools, CRM access and omnichannel communication tools to work effectively from anywhere.

Improve onboarding & training

Well-trained agents can be far more productive and less stressed. 

Create a comprehensive training program that covers everything from product knowledge to best practices and escalation protocols. Ongoing training helps agents build confidence while managers actively monitor performance and suggest improvements.

Provide better tools  to distribute the workload

Confusing processes and a lack of proper support can increase agents' stress. To mitigate this, use data and insights to identify pain points, streamline workflows, and simplify processes. 

Try implementing AI-powered chatbots to handle initial customer interactions and skilled-based routing to forward calls to the most appropriate agent.

Provide clear career paths

Outline clear career paths to show your agents that there’s growth for them. Outline the steps involved, the skills required, and the potential benefits in store for them. Also, you should provide avenues for professional growth through mentorship, training, and skill development. 

Additionally, schedule regular performance evaluations and career discussions to monitor progress and offer support. This will motivate the agents to stay with the company.

Reward & recognize

Create a formal recognition program that acknowledges and celebrates good performance through public recognition, monetary rewards, or other meaningful incentives. 

Additionally, introduce leaderboards and competitions to create friendly competition and motivate agents to perform better.

Review & learn from exit interviews

Use exit interviews to gather candid feedback on workplace experiences and obstacles. Ask open-ended questions to encourage honest feedback on their experiences, management interactions, and workplace challenges. 

Look for trends in responses and make necessary changes to address the root causes of turnover.

Voice commerce is a $421.7 billion opportunity.

Yes, more than 27% of U.S. consumers made online payments with voice assistants instead of manually browsing multiple screens and navigating the checkout process. Devices like Amazon Echo, Google Home, and Samsung SmartThings now act as virtual shopping assistants.

With the number of voice search users anticipated to reach 157.1 million by 2026, voice commerce opens up a faster purchasing channel. For businesses, this means a higher conversion rate, stronger sales, and streamlined customer support.

In this blog post, we’ll explore voice commerce, how it works, and its benefits for your business.

What is voice commerce?

Voice commerce, or v-commerce, is a technology-driven shopping experience that allows customers to search for, purchase, and manage orders using voice commands. It reduces the reliance on screens and keyboards during the buying process.

The technology relies on two components: smart speakers that convert speech into digital commands and AI assistants that interpret these commands and take action. Customers can shop hands-free while cooking, driving, or multitasking.

How does voice commerce work?

The process starts when your customer speaks a command into voice-enabled devices. While it seems simple on the surface (the customer speaks and the device responds), the technology performs several steps to complete each task. These steps include:

• Converting speech to actionable data: Your customer's spoken command gets captured and converted to text through automatic speech recognition (ASR) algorithms. For example, when they say "buy new headphones," the system captures each word.
• Understanding customer intent: The system analyzes this text to understand what your customer wants. It breaks down the command to identify the action (buying) and the product (headphones). This involves natural language processing (NLP) to interpret the meaning behind the words.
• Finding the right products: Once the system understands the intent, it searches your product database or online store for relevant items. It pulls up matching products, prices, and availability.
• Creating the right response: Then, the system creates a response based on its findings. If multiple headphone options exist, it might ask for more specifics about the price range or features your customer wants.
• Completing transaction: The customer can then confirm their choice, and the system completes the transaction — adding headphones to the cart, processing payment, or scheduling the delivery.

When you implement voice commerce for your business, pay attention to the following:

• Speech recognition must handle different accents and background noise.
• Your product database needs clear categorization for accurate matching.
• Response systems should sound natural while providing accurate information.

Plivo’s AI voice agent makes integrating voice commerce simple. The platform combines three models: speech-to-text (STT) to convert customer voice to text, large language models (LLM) to understand customer intent, and text-to-speech (TTS) for natural responses.

Here's how an interaction with Plivo’s AI voice agent flows:

Customer: "I want to buy a new dress."

AI voice agent: "What style or color are you looking for?"

Customer: "A red cocktail dress."

AI voice agent: "We have red cocktail dresses in stock. What size do you need?"

Customer: "Medium."

AI voice agent: "Found a medium red cocktail dress. Ready to check out?"

Customer: "Yes."

AI voice agent: "Order confirmed. Delivery in three business days."

Each question narrows down options until the customer finds exactly what they want. The system handles real-time conversations with minimal latency and can process and respond to mid-speech interruptions.

Plus, you can train it on your product database and business rules to deliver relevant, contextual responses.

You also control the tech stack behind these interactions. Integrate Plivo with your preferred tools for speech recognition (like Deepgram), language processing (OpenAI), and voice generation (ElevenLabs).

Benefits of voice commerce for business

Let’s now look at what voice commerce means for your business.

Increased key sales metrics

Voice assistance commerce will claim nearly 30% of all e-commerce revenue by 2030. It directly impacts the sales metrics and drives growth through:

• Increased conversion rates: Instead of manually searching for items, customers have to speak to get instant tailored recommendations. This makes shopping more intuitive and reduces drop-offs, leading to a higher conversion rate.
• Reduced cart abandonment rates: Many customers abandon carts due to lengthy or complex checkout processes. Commands like “Buy this now” or “Complete my order” will reduce friction and promote seamless shopping experiences.
• Improved customer lifetime value (CLV): Simplified reordering of previous purchases increases sales frequency and long-term customer retention. Customers can simply say, “Reorder my protein powder” or “Buy the same shampoo as last time.”
  
  • Impact:
    
    • Reduces effort, making repurchasing quick and effortless
    • Customers stick with the brand due to convenience
    • More frequent purchases → Higher CLV

For example, Starbucks integrated voice ordering through Amazon's Alexa for customers to place orders via voice commands. This led to a 16% higher monthly revenue per user from customers who used the feature.

Reduced support cost

Voice commerce reduces support costs as it handles routine customer inquiries with ease. Your support team can focus on complex issues while the voice system manages common questions about order tracking, store hours, and product information.

The system operates 24/7, so customers get immediate answers without waiting for support staff. This self-service approach cuts call volumes and support queue times. Plus, voice assistants can manage multiple customer conversations simultaneously, eliminating additional staffing costs.

Improved customer experience

82% of customers report that personalization drives brand choice. With tailored recommendations and natural conversations, voice agents let customers connect with your brand on their terms.

For example, Domino's virtual voice ordering assistant, Dom, handles customized orders, suggests additions, and finds the best deals.

Beyond convenience, voice commerce helps collect direct customer feedback to improve your service. Customers can quickly share their thoughts through simple voice commands, helping you understand and address customer needs faster.

Challenges of voice commerce

Voice commerce brings three core challenges you need to consider.

Technological complexity

Voice commerce relies on expertise in NLP and voice recognition technology to get started. The system must accurately capture and convert voice commands to text, even with different accents and noisy backgrounds. Misinterpretations of customer queries can affect the entire brand's reputation and reduce customer satisfaction.

Invest in advanced NLP and machine learning algorithms to improve performance. Partnering with a voice-first vendor like Plivo gets the task done through high-quality, low-latency audio and context-aware interactions without a hitch.

Security concerns

Voice commerce shoppers often worry about their data being recorded, stored, and potentially shared with third parties since AI handles sensitive customer data.

This system requires extra security layers for data protection and purchase verification. Businesses must address potential vulnerabilities to prevent fraud or unauthorized access through sophisticated encryption techniques.

Integration challenges

Your voice platform must connect with your e-commerce infrastructure, inventory management, payment processing, and customer data systems. The system should also sync with your product database for accurate pricing, availability, and descriptions.

While platforms like PayPal support voice transactions, many payment systems and banks don't offer voice commerce capabilities yet.  This can slow implementation and limit your growth potential until more providers adopt voice technology.

Measures to make voice commerce the next big thing

Voice commerce relies on advanced technology, but making it right doesn’t have to be complicated. Let’s look at measures to ensure its success and drive customer engagement.

Boost discoverability with voice search SEO

Voice search behavior differs from text — your customers speak in full sentences of 6-10 words. They ask, "Show me high-performance running shoes under $100" instead of "running shoes." So, connect your catalog with search engines and optimize product descriptions for these longer, conversational searches.

With 18% of global consumers using voice shopping weekly, discoverability improves when you optimize for natural speech patterns.

Streamline purchases with voice-activated shopping

Set up quick voice checkout flows and minimize steps between product discovery and purchase.

Nike launched Adapt BB shoes through Google Assistant. Fans bought the entire stock in six minutes using voice commands during an NBA game halftime. The launch proved voice shopping can drive quick sales when you make purchasing effortless.

Deliver hassle-free support with voice AI

Train your voice AI on common customer issues. Build responses for tracking, returns, product specs, and shipping questions. Update the system with new products and policies. For example, 1-800-Flowers runs voice self-service for customers to track orders, change delivery details, and check FAQs. This support channel works 24/7, letting customers get help when they need it.

Track voice commerce performance

Set clear metrics for your voice channel and use insights to refine your strategy. Track voice-activated sales, search volume, and support requests. Monitor how voice affects customer behavior. Do they order more often? Place bigger orders? Buy different products?

Analyze patterns and optimize voice interactions to improve customer engagement and maximize ROI. Voice support cuts operational expenses, and self-service options reduce agent workload. This automated ordering speeds up sales processing.

Turn customer insights into smarter strategies

Update your voice features based on user needs. Fix common pain points, add requested features, and remove unused options.

Estée Lauder's voice-enabled makeup assistant (VMA) collects user input during key moments of the experience. Customers share thoughts through voice commands or the feedback menu. Their app updates reflect direct user feedback.

Voice commerce then, now, and beyond

From basic speech recognition to sophisticated shopping systems, voice commerce has evolved so much. Here’s a timeline of the evolution:

• IBM's 1961 "Shoebox" could understand just 16 spoken words.
• In 1971, Carnegie Mellon's "Harpy" system processed 1,000 words through DARPA funding.
• The real breakthrough came in the 1980s when Dragon Systems brought speech recognition to personal computers.
• The 2010s marked the shift to mainstream voice commerce adoption:
  
  • Apple's Siri (2011) introduced voice assistance to millions of iPhone users.
  • Amazon's Alexa voice assistant (2014) transformed voice shopping by connecting speech recognition with e-commerce.
  • Google Assistant (2016) joined the voice commerce market, driving competition and innovation.

Today, voice commerce is no longer used just for single-store transactions. Businesses can now integrate with multiple voice platforms — Alexa supports transactions for Walmart, Best Buy, 1-800-FLOWERS, and Starbucks. Customers only need to link their retail accounts to start voice shopping.

REI Co-op, Redbox, and eBags also use the platform to distribute deals and track orders.

Apple Store handles peer-to-peer payments through Siri. Walmart's mobile app tests hands-free shopping, order scheduling, and voice-based customer support.

The market shows strong growth potential. Research projects voice commerce to grow at a CAGR of 24.34% annually from 2024 to 2030. That means v-commerce is slowly becoming a necessity to stay competitive for businesses.

Natural language processing (NLP) works behind the scenes in places you might not even notice — filtering spam emails, customer service chatbots, and even accurate Netflix recommendations. It’s woven across industries and is rapidly evolving, with the market projected to hit 156.76 billion by 2030.

It's natural to wonder whether NLP is too complex or worth integrating into your systems. This guide offers five digestible NLP steps so you can understand how the technology works and whether it’s a good fit for your business.

What is NLP?

Simply put, NLP lets a machine understand, interpret, and respond to human language, written or spoken. It's the reason voice assistants listen to your commands, chatbots answer your queries, and search engines predict what you’re looking for even before you finish typing.

The NLP process is powered by two key components.

Natural language understanding (NLU) helps machines decode what humans mean, even if the content isn't totally clear. For example, customer support chatbots use NLU to recognize when a user is frustrated (based on words like “poor service” or “I need help now”) and escalate the issue appropriately.

Once the machine understands what the user is saying, natural language generation (NLG) generates a response in a way that sounds natural. Instead of just responding with pre-set phrases, the system personalizes the response based on the user’s request, offering logical next steps, similar to how a human agent would.

Here’s a quick rundown of the stages of NLP:

• Splits sentences into smaller chunks (tokenization in NLP) for easier processing.
• Identifies keywords, grammar, and structure to understand context.
• Detects names, dates, locations, and brands (e.g., virtual assistants retrieving order details).
• Determines if a message is a question, request, or complaint for accurate chatbot/voice assistant responses.
• Assesses tone and emotions to gauge customer satisfaction in chats.

To better understand NLP techniques, let’s go through the most common everyday NLP applications.

Most common everyday NLP applications

Along with autocorrecting and filtering spam emails, NLP is most commonly used in the following use cases:

• Chatbots and virtual assistants: NLP enables AI chatbots in customer service to understand and respond to human language, improving customer support and user engagement. These virtual assistants handle tasks like answering FAQs, scheduling appointments, and providing 24/7 customer service, mimicking human interactions to improve efficiency.
• Language translation: Tools like Google Translate use NLP to provide real-time multilingual support. You use this to communicate with global customers and break language barriers in customer service.
• Sentiment analysis: How does a machine know when a caller is frustrated, angry, or simply uninterested in your product? Sentiment analysis scans customer reviews, support tickets, or even social media mentions to determine if the feedback is positive, negative, or neutral. You can use it to gauge customer opinions.
• Speech recognition and voice AI: Speech recognition converts spoken words into text which helps businesses with real-time transcription, AI-driven interactive voice response (IVR) responses, and improved call routing. An advanced ASR (automatic speech recognition) tool like Plivo also masks inappropriate content in transcriptions and improves speech recognition accuracy by providing a list of hint words expected from the caller.

Now that we know about the most basic everyday NLP applications, let’s understand the five NLP steps in detail. 

5 steps in natural language processing

Let’s go through the five steps in NLP with examples.

Step #1: Lexical analysis

Text preprocessing in NLP precedes lexical analysis as it undergoes cleaning, tokenizing, and structuring raw data to make it readable for NLP models.

A study emphasizes that understanding grammatical structures and keywords is vital for chatbots to provide coherent and relevant responses in real-world situations. Lexical analysis helps NLP do so, making it one of the most important natural language processing steps.

It converts a sequence of characters into a sequence of tokens. This tokenization in NLP deciphers and segments languages into units (lexemes), such as sentences, phrases, and words.

Some words can stand alone, like “cat” or “jump”. These are free morphemes because they don’t need any extra help to be complete words. However, then there are bound morphemes, which have to latch onto something else to make sense. For instance,  “replaying”:

• “re-” (a prefix meaning “again”)
• “play” (the root word that holds the meaning)
• “-ing” (a suffix showing it's happening right now)

Neither of these words can exist alone, they always need a root word to stick to.

Machine learning in AI plays an important role in lexical analysis by helping NLP systems continuously improve their ability to identify and segment words accurately. When NLP analyzes text, it goes through a process to understand these layers, which helps understand word meanings, grammatical structures, and even how words change depending on context.

Lexical analysis teaches AI to deconstruct language the way the human brain does, but faster.

Step #2: Syntactic analysis

Syntax is the foundation of language, it’s how words and phrases come together to form meaningful sentences. Syntactic analysis (or parsing) lets NLP systems understand sentence structure and relationships between words rather than analyzing them in isolation.

This ensures that AI-powered chatbots, smart IVR systems, and voice assistants interpret user queries correctly.

When NLP performs syntactic analysis, it:

• Identifies sentence structure: Breaks a sentence into subject, predicate, objects, clauses, etc.
• Determines relationships between words: Determines which words depend on or modify others.
• Checks for grammatical correctness: Ensures the sentence follows valid language rules.

Syntactic analysis is important for chatbots and virtual assistants to improve customer experience with smart IVR. When a customer says, “I need help to reset my password”, the system uses syntactic analysis to recognize:

• “I” as the subject
• “need help” as the action
• “resetting my password” as the specific request

This structured understanding helps the AI respond appropriately, directing users to the right solution without confusion or misinterpretation.

Step #3: Semantic analysis

Semantic analysis in NLP deciphers meaning based on context, intent, and sentiment. The same word or phrase can imply different things depending on how it's used, and semantic analysis ensures AI comprehends these nuances accurately.

For instance, if a caller says, "I need to cancel my order because I wasn’t happy with the last one," a basic AI might fixate on the keyword "cancel" and proceed with the request.

But a Plivo-powered voice agent with semantic analysis understands the full context. It detects dissatisfaction from "wasn’t happy with the last one" and responds empathetically:

• “I’m really sorry about your previous experience. Let’s make this right.”
• Apart from processing the query, it might offer a resolution: “How about a 20% discount on your current order as an apology?”

Semantic analysis helps voice agents understand natural conversations instead of just keywords. This context-aware approach makes customer interactions more human, but you can also use these voice transcriptions for customer analytics to make informed decisions.

Step #4: Disclosure integration

Discourse integration helps NLP models grasp the broader meaning of conversations by considering previous sentences for context. This ensures more accurate interpretations and reduces confusion in AI-driven interactions.

For example, in a customer support chat:

Caller: "I lost my credit card yesterday."

Bot: “I’m sorry to hear that. Would you like to report it as lost or request a replacement?"

Caller: “Cancel it.”

Without discourse integration, the AI might struggle to understand whether the user wants to cancel the report or the card itself. By analyzing the conversation history, it correctly determines that "cancel it" refers to the lost card and proceeds accordingly.

This is important for businesses to automate customer interactions, and ensure smarter, context-aware responses in finance, healthcare, and beyond.

Step #5: Pragmatic analysis

Pragmatic analysis interprets meaning based on context, tone, and real-world knowledge rather than just literal word definitions so that the conversations feel natural and relevant. For instance, when a user asks, "What's the price of your premium subscription plan?"

The bot responds with, "Sure, our premium starts at $50 per month.”

Now, if the user simply responds, "That's a little steep," the bot automatically suggests, "Would you like to explore our standard plan starting at $30?"

While the user doesn't explicitly mention they want to explore a lower-priced option, pragmatic analysis recognizes the implied concern and suggests an alternative.

Businesses benefit from this by providing better customer engagement, fewer misunderstandings, and more effective automation.

While the steps in NLP help make customer experience better, it’s not all pros. 

Challenges and future advancements in NLP

One of the biggest NLP challenges is the bias in AI models.

Since AI learns from human data, it can reflect societal biases, leading to unfair or misleading outputs. MIT researchers developed a technique that reduces bias in AI models while preserving or even improving their accuracy for fairer and more reliable AI decision-making.

Another challenge is understanding regional dialects and slang. Many NLP models struggle with informal speech, code-switching, and cultural nuances, making accurate interpretation difficult in multilingual or diverse environments.

Ethical concerns, such as misinformation, privacy risks, and deepfakes (AI-generated content that falsely mimics real people) add to the complexity.

Looking ahead, context-aware AI conversations will improve chatbot and virtual assistant interactions, making them more natural and relevant. Real-time speech translation is also advancing, aiming for easy, culturally aware translations without robotic phrasing. As NLP evolves, voice integration in conversational AI will focus on making AI communication more inclusive, ethical, and human-like.

Clearly, AI voice intelligence in customer service is leading the charge.

However, despite its benefits, many business owners still wonder: will automation make customer interactions feel robotic? More importantly, how do you use voice AI in a way that actually improves customer experience?

This guide will break it all down — what voice intelligence is, how businesses use it, and the real impact it has on customer interactions across industries.

What is voice intelligence?

Voice intelligence is an AI-powered system that can understand, interpret, and respond to spoken language the way humans do.

Unlike conventional interactive voice response (IVR) systems, which rely on rigid menu-based navigation, natural language processing (NLP) in voice AI listens to callers' words, processes their intent, and delivers relevant responses.

For example, Apple's Siri goes beyond setting alarms or reminders and asks follow-up questions to maintain context in a conversation. Similarly, Google’s Gemini can summarize web pages, suggest replies, and help you with booking appointments. 

But how does it actually work?

How voice intelligence works

Voice intelligence combines AI tools like NLP, machine learning, and real-time AI-powered speech analysis to analyze calls, voicemails, and digital conversations, helping businesses respond faster and more accurately.

This means they can catch key issues, offer better support, and even automate certain interactions, without losing the human touch.

Let’s break this down with a use case.

User A calls their bank’s support line after noticing an unfamiliar charge on their credit card.

Speech recognition converts voice into text

At the core of voice intelligence lies speech recognition. It converts spoken words into text and allows AI-powered voice agents to "listen" to a caller.

Going back to our example where the user calls their bank, here’s what happens behind the scenes:

When they say, "I see a charge I don't recognize on my card.", the speech recognition gets to work. It transcribes the words into text, identifies individual words, corrects minor pronunciation errors, recognizes the accent, and captures the intent without losing context.

Plivo's automatic speech recognition (ASR) takes it a step further. It filters inappropriate content in transcriptions, supports speech recognition in 27 languages, and offers pre-built models for different industries.

So if the user uses rash language like “I’m pissed off with this bank”, the ASR identifies “pissed off” as inappropriate and removes it from the transcript. At the same time, it correctly interprets 'charge' in the context of financial transactions, avoiding confusion with alternative meanings such as charging a device.

NLP understands intent and context

NLP in voice intelligence recognizes accents, slang, and even sentiments. It actually grasps the meaning behind those words the way humans do.

When the user says, "I see a charge I don't recognize on my card," the system, using NLP, identifies key terms like “charge” and “don't recognize” to understand that the user is reporting a potentially fraudulent transaction.

If such an interaction has occurred in the past, machine learning in voice intelligence learns from it and improves its ability to detect predictable phrases like "unauthorized charge," "fraud," etc. It also detects a spike in customers calling about fraudulent charges in the future.

AI-driven decision-making determines the right response

After the call gets transcribed and analyzed, AI taps into past interactions to offer a faster, personalized resolution. For instance, if the user has travel alerts active on their account, AI determines the charge is legitimate and reassures them.

If the user expresses urgency with phrases like, "It's serious", or "I need to talk to a specialist now", AI picks up on the tone and escalates it to a human fraud specialist. 

But even the smartest voice AI can only make good decisions with high-quality voice data.

Plivo’s call analytics plays a vital role by identifying audio issues like poor network conditions, background noise, or low call clarity. It correlates audio quality metrics with device metadata and network conditions so that businesses can ensure AI decisions are based on accurate, uninterrupted speech data.

This leads to better fraud detection, sentiment analysis, and overall customer experience.

Text-to-speech (TTS) helps bots sound human-like

While voice recognition AI converts the call into text, text-to-speech (TTS) does the reverse. It converts the AI-generated responses into natural, human-like speech.

TTS gauges intent adapts to different accents, and structures responses naturally. Instead of a robotic reply, it might say, “I understand that an unfamiliar charge is concerning. Let me check that for you.”

For urgent cases, it might say, “Let me transfer this call to our fraud specialist right away.”

Unlike stiff, pre-recorded messages, TTS adapts to each conversation in real-time, making AI-powered voice responses feel more human and helpful.

This brings us to our next question: what are the benefits of voice intelligence?

Benefits of voice intelligence for businesses

Now that we know how voice intelligence works, let’s understand its benefits for businesses.

Scalability: Never leave a customer on hold

Voice intelligence enables businesses to manage customer interactions efficiently, regardless of call volume. AI-powered tools ensure immediate attention for every customer, eliminating long wait times and improving satisfaction.

For example, a retail business may experience a surge in inquiries about shipping, returns, or product availability during the holiday season. Voice intelligence deploys agents to answer common questions like "What is your return policy?" or "When will my order arrive?" for multiple customers at the same time.

For calls requiring human assistance, the AI gathers details such as order numbers or the nature of the issue beforehand, helping representatives resolve concerns more quickly.

What’s more, AI can offer callbacks instead of making customers wait on hold, keeping frustration levels low and satisfaction high.

Reduced costs: Say goodbye to excess customer support hiring

Since AI-powered voice agents handle repetitive inquiries, it reduces the workload for human agents. Businesses don't need to hire extra staff to manage call spikes. Plus, during high call volumes, it absorbs extra demand, keeping customer service intact without additional payroll expenses.

AI-powered voice agents also learn instantly and require no training, further reducing the overhead of onboarding new employees.

Increased customer satisfaction: Make context-aware conversations in multiple languages

Become, a financial technology company, integrated Plivo's Browser SDK to enable high-quality voice calls within their web application.
