'''Speaker verification''' (also called '''speaker authentication''') contrasts with identification, and '''''speaker recognition''''' differs from ''[[speaker diarisation]]'' (recognizing when the same speaker is speaking).

Recognizing the speaker can simplify the task of [[speech translation|translating speech]] in systems that have been trained on specific voices or it can be used to authenticate or verify the identity of a speaker as part of a security process. Speaker recognition has a history dating back some four decades as of 2019 and uses the acoustic features of speech that have been found to differ between individuals. These acoustic patterns reflect both [[Human anatomy|anatomy]] and learned behavioral patterns.
