PROBLEM TO BE SOLVED: To perform suitable speech correction processing according to the voice quality of a speaker. SOLUTION: When a speaker's voice is inputted from an input section 11, an analysis section 12 performs frequency conversion processing such as Fourier transformation to calculate a feature spectrum of an input speech signal. Then a reference spectrum for male and a reference spectrum for female are read out of a storage section 13 and difference spectrums thereof are calculated respectively. Then the similarities of the voice with standard voices are determined according to the difference spectrum, and the difference spectrum obtained from the reference spectrum having the higher similarity is determined to use for subsequent processing and supplied to a correction processing section 14. The correction processing section 14 corrects the speech signal according to the supplied difference spectrum. An output section 15 perform sound radiation processing according to the speech signal having been corrected. COPYRIGHT: (C)2006,JPO&NCIPI
