Q6.6: Speaker Recognition (Verification and Identification)


Speaker recognition is the process of automatically recognizing who is speaking on the basis of individual information included in speech signals. It can be divided into Speaker Identification and Speaker Verification. Speaker identification determines which registered speaker provides a given utterance from amongst a set of known speakers. Speaker verification accepts or rejects the identity claim of a speaker - is the speaker the person they say they are?

Speaker recognition technology makes it possible to a the speaker's voice to control access to restricted services, for example, phone access to banking, database services, shopping or voice mail, and access to secure equipment.

Both technologies require users to "enroll" in the system, that is, to give examples of their speech to a system so that it can characterise (or learn) their voice patterns.
