<p><P>PROBLEM TO BE SOLVED: To provide a featured value capable of highly accurately recognizing a speaker. <P>SOLUTION: A feature extraction section 32 calculates an autocorrelation sequence AV of frequency components of a voice signal V exceeding a predetermined frequency fc as a featured value FV. The autocorrelation sequence AV is a sequence (time sequence) of an autocorrelation value a(m) of a voice signal V. A storage section 24 stores an autocorrelation sequence AREF for reference. A speaker recognition section 34 performs speaker recognition by comparing the autocorrelation sequence AV of the voice signal V with the autocorrelation sequence AREF for reference. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
