Passive Voice Biometrics
An approach to using Voice Biometrics that does not require the user to do anything additional to their reason for calling or interacting with a speech service for authentication or enrolment.
This form of Voice Biometric authentication often takes place in the call background, as the user is speaking to an agent or interacting with a speech-driven application. Because the user is not required to do anything that they would not otherwise have done, we refer to this as Passive.
The genuine user will usually have enrolled during registration on a previous interaction after registration with an agent or automated system. The only additional effort required for registration is the process of giving consent.
