In an input voice pitch normalization device (Tr) equipped in a voice recognition device (VRAp) for recognizing an input voice (Svc) uttered by unlimited speakers, and used to change a pitch of the input voice (Svu) to be in a predetermined relationship with voice recognition sample data (Psf), a pitch difference determination device (3, 5, 7, 9; #100, #200, #300, #400) determines a pitch difference (CR) between said input voice (Svu) and said voice recognition sample data (Psf), and a pitch change device (11, 3; #500) changes, based on the pitch difference (CR) determined by said pitch difference determination device (3, 5, 7, 9; #100, #200, #300, #400), a frequency of the input voice (Svu) in such a manner as to make the pitch of said input voice has a predetermined relationship (CR = 1) with the pitch of said voice recognition sample data (Psf). <IMAGE> |
