The relation of speaker verification to other pattern-recognition problems in speech is discussed, especially the distinction between speaker verification and speaker identification. The prospects for automatic speaker verification, its settings and applications are outlined. The techniques, evaluations, and implementations of various proposed speaker recognition systems are reviewed with special emphasis on issues peculiar to speaker verification. Two large-scale operating systems using different analysis techniques and applied to different settings are described.
