Voice Biometrics Market: Pros and Cons

The promise of voice biometrics as a magic bullet for reducing fraud risk in contact centers was highly anticipated. It suggests a powerful tool for combating security threats. The voice biometrics market functions like physical fingerprints. It verifies identity during phone conversations to provide a layer of security. It also offers the advantage of almost entirely automated identity verification. As a result, fewer human interventions are necessary.

Voice biometrics works by recognizing specific identifying features of a speaker’s voice rather than the spoken words. These unique traits are determined by individual anatomical and speech pattern differences. Factors like the anatomical structure of our mouths and speaking habits (like how fast or slow we talk) influence our voices. The attributes combine to create a distinctive voice that is recognizable to others.

Voice biometrics involves mapping a speaker’s unique traits to generate a personalized voiceprint from audio samples. When the user calls in, the software compares the live voiceprint to the stored one. This method ensures each voice is as uniquely identifiable as a fingerprint.

To implement voice authentication which uses an individual’s unique voice for security, two key elements are needed. First is a device capable of capturing a person’s voice with high precision. Second is a software which can analyze and match these voice patterns to pre-stored ones.

Voice authentication uses distinct voice patterns to verify and grant access to users. Unlike speech recognition that is concerned with understanding spoken words, voice authentication focuses on identifying the individual speaker. The process relies on an individual’s unique voice. It represents the specific sound and pattern of their voice digitally or numerically. This biometric is comparable in uniqueness to iris patterns or fingerprints.

It is pivotal for verifying speakers. When integrated with password and PIN, it delivers two-factor authentication for accessing secure locations and materials. Researchers have also applied voice biometrics to distinguish individual wolves in National Park in Yellowstone based on their howls.

Many scammers have refined their tactics to overcome standard security measures in call centers. That includes security passwords and questions. They use information from social media and trick agents through ineffective authentication practices. Adopting voice biometrics technology helps a call center protect against scammer methods and enhance the safety of customer interactions.

A prominent market research firm, GMI Research, estimated that the voice biometrics market size touched USD 1,749 million in 2022 and would reach USD 8,695 million in 2030. This rapid growth is owing to the rising requirement for fraud identification and prevention along with the robust digitalization across the globe.

While voice biometrics might offer a robust security solution for your contact center, you should address several considerations before making it the sole method of verification.

The Benefits

Many organizations recognize the importance of the voice biometrics market because of its many benefits. The growing investment and interest in voice biometrics have led to numerous technology companies pursuing patents in this area.

Someone’s voice is difficult to spoof

Identity thieves may obtain a customer’s birth date and unique information such as their mother’s or pet’s name. Yet, a unique voiceprint is considerably more challenging to acquire or counterfeit.

Convenience

Using voice biometrics for authentication is more user-friendly than entering passwords or remembering answers to security questions. With voice-based identification, there is no reliance on memory as the voice itself provides authentication.

Foster automation

With voice biometrics, consent can be automatically verified after identity confirmation. An automated IVR system might request permission for call recording. Meanwhile, voice biometrics ensures that the consent was provided by the genuine customer.

Potential disadvantages

From the start, it is crucial to understand that the voice biometrics market is still an evolving technology. It requires complex AI algorithms, extensive datasets, and real-world validation.

Risk of racial bias and discrimination

It is important to remember that voice algorithms particularly those designed for identification rather than verification, need diverse training datasets with a wide range of voices. However, studies reveal that many popular voice technologies may be trained on datasets that are racially biased. This can result in better performance for certain demographics over others.

Consent and privacy

Since voice is an intensely personal trait, many customers may be hesitant to share their voice samples. Ensuring compliance with data privacy regulations can be difficult because it’s easy to collect voice samples. Critics have accused the Chinese government of potentially violating privacy rights by gathering voice patterns to create a national database.

Deep fake for voice

Finally, as deep fakes for audio become more sophisticated, they could deceive AI into accepting fake audio samples as authentic. It is challenging for the accuracy of the systems in the voice biometrics market.
