Is voice better than other biometrics factors?
Voice is comparable to other biometrics in many ways. However, voice does have some advantages, not least because the user doesn’t need a scanner, such as for iris and fingerprint recognition.Voice is extremely easy to use and, because of that, it has a higher level of user acceptance than many other biometric identity verification methods. In terms of accuracy, voice is broadly equivalent to other methods, and it is no less secure than fingerprints, retina, or facial recognition. Essentially, voice is both convenient and reliable, not having to be concerned with residues or poor lighting.
A primary advantage of voice is that it is the only biometric technology that can be used remotely over the telephone. That means it is particularly suitable for authenticating callers to a contact centre or an inbound, IVR-driven self-service platform. In a similar way, it can be used to verify the identity of people called from an outbound contact centre solution.
