Voice Biometrics (VB) is used to detect and verify a caller’s identity that has been authenticated in a past call.
The basic steps for VB to operate are the following:
VB verification. Comparing the active voice stream against stored voiceprints.
VB enrolment. Authoritatively assign a set of identifiers to a stored voice recording.
VB opt out. Remove a user from the VB service if requested.
VB verification system expectations. Speaker verification systems calculate the similarity score between two or more voiceprints from the same speaker. They differ from speaker identification systems, where the goal is to identify who is speaking amongst a set of speakers.
