Speaker Verification; is the process of verifying someone’s voice against a claimed identity. It is a 1 to 1 matching process where audio is checked against a (single) previously enrolled voice model (the voice print). The goal is to assert the individual is or is not who they are claiming to be, generally for the purpose of authentication.
Speaker Identification; is the process of checking spoken audio against multiple pre enrolled voice models. It is a 1 to N process as there is no claimed identity, the system is trying to establish who the speaker is from their voice. It is often used for techniques such as watchlist (e.g. identification of known fraudster) processing or agent identification.
ValidSoft’s VB engine performs both verification and identification and can perform both in parallel.
