Using voice biometrics to authenticate if the person is who he/she is claiming to be is very much in use these days.

 What Exactly Is Voice Biometrics?

In this technology, a phrase spoken by a person is captured by a sophisticated system and is then compared with the previously stored voiceprint. All this happens simultaneously while a person is speaking. Identifying a person by voice is a complex task. This is because the voice is influenced by scores of factors, which can be physical or behavioral.

The voiceprint is algorithmically derived and this algorithm generates a voiceprint making use of different calculations. The behavioral and physical characteristics provide a unique digital representation.

Working of Voice Biometrics

In the very first call with the customer, the biometric software registers the voice sample. This happens in the background while the customer is in conversation with the agent. The sophisticated statistical algorithm after recording and analyzing the voice of many distinctive characteristics creates a voiceprint or biometric model. This model is then encrypted and stored in a secure database.

When a customer makes subsequent calls, the system automatically creates a voice model and then compares it with the stored sample. The result then gets displayed on the operator’s monitor. If it displays successful authentication, the operator doesn’t require any further identification from the customer.

In case you are worried that the voice may be mimicked and thus someone good at mimicry can fool this system, be rest assured. The voice of a person is as unique as the retina or fingerprints. An impersonator can copy the pitch and the intonation, but the other physiological features like the vocal cord location and larynx structure are unique to a person. It is impossible to fake all these characteristics.

Applications of Voice Biometrics

Voice biometrics is an incredibly versatile technology that finds use in several areas. Listed below are few unique applications that prove the strengths of this voice-based authentication method.

  • Call Center Authentication: It’s not easy to prove your identity over the phone, but having a voice-based identification system in place can allow for strong identification proof. In call centers, voice biometrics can enhance fraud protection, improve the consumer experience, cut down call time and cost, and maintain your brand identity.
  • HandsFree Interface: Voice biometrics in association with speech commands can enable interfacing with connected vehicles and devices, while simultaneously offering identification at biometric levels.
  • Protect Bank Account: Voice biometrics can be used along with facial recognition technology to serve as an extra level of security in the process of authentication for bank transactions.
  • Mobile Application Development: The software-oriented nature of voice biometrics makes it a secure technology to be used in the development of mobile applications for protecting in-app payments or transforming the smartphone into a biometric credential.

With the secure level of authentication that voice biometrics offers, there’s no doubt that this technology will come with many more advancements and applications in the days to come.
