Voice verification is an authentication method that many businesses are quick to adopt. Also, known as voice biometrics, it uses the user’s unique vocal characteristics to verify their identity. Therefore, in the B2C setting, you will find it in the form of a voice verification code.
In this guide, you are going to get a deeper understanding of this groundbreaking practice. In addition to this, you will find easy steps on how to implement it and enhance the security of your business.
Part 1: What is Voice Verification? What’s So Special about It?
Definition & Objective
Note
Voice verification belongs to the wide group of biometric technologies, just like fingerprint verification. What makes it stand apart is that it identifies and authenticates each user based on the unique characteristics of their voice. These characteristics are significantly distinct from person to person as they are influenced by physiological and behavioral factors, making it hard to replicate.
The primary reason for switching to a voice verification code method is to provide a secure and convenient method for user authentication.This way, you can reduce reliance on traditional credentials, such as passwords, that can easily be compromised. Therefore, if you are looking for a way to enhance your security, this is definitely a technology that you need to adopt.
Difference Between the Voice Verification Code and SMS Verification Code Methods
As you may already understand, voice authentication has a very similar objective to that of SMS verification. While both practices aim to authenticate users, they operate in very different ways.
In the SMS verification code method, users receive a one-time code via text message. Then, they need to enter this code to the app or website they are using to verify their identity. However, it is important to understand that this particular method relies on the security of the user’s device and network.
In the voice verification code method though, the user’s identity is confirmed by analyzing their unique vocal characteristics during a spoken interaction. This method takes advantage of biometric data, which are inherently unique to each individual, thus making it one of the securest methods. It is worth mentioning that a voice verification code scam is not that common compared to other phishing attempts.
To help you better understand how these methods compare, we have compiled this table:
| Feature | Voice Verification | SMS Verification |
|---|---|---|
| Security Level | High as it’s difficult to replicate a voiceprint | Medium since codes can be intercepted or phished |
| Usage Method | Hands-free and password-free authentication | User has to enter the code manually |
| Reliability | May be affected by background noise or voice changes | May be affected by SMS delays and network disruptions |
| Fraud Prevention | Detects anomalies and fraud attempts through AI | Prone to phishing attacks |
| Use Cases | Call centers, banking, healthcare | Website logins, mobile app authentication |
| Privacy Concerns | Biometric data storage requires compliance with regulations | Requires users to provide the apps with their personal phone numbers |
Advantages and Challenges of the Voice Verification Code Method
If you find that voice verification is the best choice for your business, it is definitely a technology you should try. In more detail, its advantages are the following:
- Enhanced Security: Voice biometrics are really difficult to replicate. By utilizing them, you will reduce the risk of unauthorized access as a voice verification code scam is unusual.
- User Convenience: Users can authenticate their identities naturally through speech without the need to remember a password or code.
- Fraud Detection: This technique is great at detecting anomalies in voice patterns, thus making it easier to identify potential fraudulent attacks.
Despite its many benefits that it will bring to your company, voice authentication also has some challenges. If you are already familiar with them, you can find ways to predict and bypass them. The challenges of voice verification are the following:
- Background Noise: The environment can directly interfere with accurate voice recognition. For instance, if the user is in a noisy setting, then the data might not get captured correctly.
- Health Issues: There are many illnesses that temporarily alter a person’s voice, such as the common cold. In this instance, the authentication process might fail as the system won’t be able to recognize the vocal characteristics of the user.
- Privacy Concerns: Biometric data are delicate, and for this reason, they are protected by laws. If you want to store and process this type of data, you need to ensure that you comply with the laws and regulations of each region.
Part 2: How Does Voice Verification Code Work & Common Application Scenarios
The Technical Basis of Voice Verification Software
Now that you know what voice authentication is, you might be wondering how it actually works. A voice verification system works by capturing the user’s vocal "fingerprint", meaning its unique features such as pitch, tone, and speech patterns.
The Industries and Scenarios for Voice Verification
The voice verification code method has already found many applications in a variety of industries. The most notable ones are the following:
- Government Services: Many users have to disclose very sensitive, personal information when dealing with government services. That’s why many of them have adopted voice authentication to protect citizens. A great implementation example in this sector is the Australian Taxation Office.
- Banking and Finance: These industries deal with sensitive information. For this reason, they use this practice to verify the identity of users during phone banking services.
- Telecommunications and Call Centers: When customers reach out to the customer support of their carriers, they often encounter this service. The companies can quickly verify the callers’ identities without delays.
When it comes to this sector, the best example comes from Vodafone. TOBi is the AI assistant that the company has implemented in their customer support. Apart from providing relevant information, it quickly verifies the callers’ identity to make the process quicker and easier.
