Speaker recognition is the identification of the person who is speaking by characteristics of their voices (voice biometrics), also called voice recognition.
There is a difference between speaker recognition (recognizing who is speaking) and speech recognition (recognizing what is being said). These two terms are frequently confused, and "voice recognition" can be used for both. In addition, there is a difference between the act of authentication (commonly referred to as speaker verification or speaker authentication) and identification. Finally, there is a difference between speaker recognition (recognizing who is speaking) and speaker diarisation (recognizing when the same speaker is speaking). Recognizing the speaker can simplify the task of translating speech in systems that have been trained on specific person's 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 and uses the acoustic features of speech that have been found to differ between individuals. These acoustic patterns reflect both anatomy (e.g., size and shape of the throat and mouth) and learned behavioral patterns (e.g., voice pitch, speaking style). Speaker verification has earned speaker recognition its classification as a "behavioral biometric".

Famous quotes containing the words speaker and/or recognition:
“English audiences of working people are like an instrument that responds to the player. Thought ripples up and down them, and if in some heart the speaker strikes a dissonance there is a swift answer. Always the voice speaks from gallery or pit, the terrible voice which detaches itself in every English crowd, full of caustic wit, full of irony or, maybe, approval.”
—Mary Heaton Vorse (1874–1966)
“By now, legions of tireless essayists and op-ed columnists have dressed feminists down for making such a fuss about entering the professions and earning equal pay that everyone’s attention has been distracted from the important contributions of mothers working at home. This judgment presumes, of course, that prior to the resurgence of feminism in the ‘70s, housewives and mothers enjoyed wide recognition and honor. This was not exactly the case.”
—Mary Kay Blakely (20th century)
