ABSTRACT:
Methods and apparatus for providing speech-based authentication, including the determination of a target discriminant based on an identity claim and on at least one target voiceprint model relating to a target speaker, of a background discriminant based on the identity claim and on at least one background voiceprint model relating to at least one background speaker, and of a score based on the target discriminant and the background discriminant, which score is used to accept or reject the identity claim.
