EVA Voice Biometrics is a second-factor voice biometric solution designed for use with a broad range of web browsers that support audio capture. The biometric verification process is intended to be part of an authentication flow to enhance security, privacy and ease-of-use. EVA Voice Biometrics is an offering from Auraya Systems.

The voice tokens used with EVA Voice Biometrics are predominantly digit strings, although phrases are also supported. The usual verification process will usually prompt the user to read out a sequence of random digits, a sequence of consecutive digits, and optionally their phone number.
