Voice biometrics is a technology used to verify a person’s identity using their unique vocal attributes. Everyone has different physical and behavioral characteristics that influence the sound of their voice and in combination these are—just like a fingerprint—unique to every individual.

The ease of use and enhanced security features makes voice biometrics the perfect replacement and/or an addition to traditional knowledge-based authentication processes.

Virtual assistants can use voice biometrics to confirm a caller’s identity as part of self-service interactions or before routing the caller to a customer service representative.
