ABSTRACT:
A speaker verification apparatus and method input an identity claim, select voice information of a registered speaker corresponding to the input identity claim, input a voice of the speaker, analyze the input voice so as to extract a feature parameter, calculate a verification distance between a feature parameter of the input voice and that of the voice of the registered speaker and the speaker distances between a feature parameter of the input voice and those of the voices of other speakers; and determine whether or not the input voice matches that of the registered speaker. A false acceptance error rate, is input as a threshold, and a probability distribution of interspeaker distances is functions to determine that the input voice is the voice of the registered person specified by the identity claim.
