Abstract: A method and system for talker authentication in which a trial speech sample from a person who may be legitimate or who may be an imposter is compared to a standard speech sample of the legitimate person. The trial speech sample forms the input to a plurality of band pass filters. The outputs of each of the filters are integrated over the duration of the speech sample and the integrated signals are normalized. These normalized signals are compared to normalized signals of a standard speech sample to generate a plurality of difference signals. The magnitudes of the difference signals are added together to generate an authenticity signal, the magnitude of which corresponds to the correspondence between the trial speech sample and the standard speech sample.
