Speaker Recognition

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:

    “There is a terrible blindness in the love that wants only to accommodate. It’s not only to do with omissions and half-truths. It implants a lack of being in the speaker and robs the self of an identity without which it is impossible for one to grow close to another.”
    —Alexander Theroux (b. 1940)

    “While you are nurturing your newborn, you need someone to nurture you, whether it is with healthful drinks while you’re nursing, or with words of recognition and encouragement as you talk about your feelings. In this state of continual giving to your infant—whether it is nourishment or care or love—you are easily drained, and you need to be replenished from sources outside yourself so that you will have reserves to draw from.”
    —Sally Placksin (20th century)
