PROBLEM TO BE SOLVED: To solve the problem that in a conventional voice processing apparatus, voice processing according to a speaker's characteristic of a person to be evaluated, who is a speaker of voice, cannot be performed, and as a result, the voice processing with high accuracy cannot performed. SOLUTION: The voice processing apparatus comprises: a sampling section for acquiring a first voice data by sampling received voice with a stored first sampling frequency; a vocal tract length normalizing processor for storing a formant frequency of the person to be evaluated which is the formant frequency of the person to be evaluated who is a speaker of the voice received by a voice receiving section, and for acquiring a second voice data by performing sampling processing on the received voice with a second sampling frequency, that is, the first sampling frequency/(formant frequency of a teacher data/formant frequency of the person to be evaluated), is performed according to the speaker's characteristic; and a voice processing section for processing the second voice data. Thereby the voice processing according to the speaker's characteristic is performed. COPYRIGHT: (C)2007,JPO&INPIT |
