Abstract
A speech of a registered speaker input from an input unit is converted by a converting unit to a sound spectrogram “A” and stored. As a speech of a speaker to be identified is input from the input unit and converted to a sound spectrogram “B” by the converting unit, a detecting unit detects a partial image including a plurality of templates placed in the registered speech image A by a placing unit, and each of areas on the unknown speech image B in which maximum correlation coefficients are calculated. Then, a determining unit compares a mutual positional relationship of the plurality of templates with a mutual positional relationship of the respective areas in which the maximum correlation coefficients are detected to determine from the degree of difference therebetween the identity between the registered speech and the unknown speech.
