PROBLEM TO BE SOLVED: To provide a voice processor and a program which convert input voices into choral voices with many people and ensemble sound by a simple configuration. SOLUTION: A pitch detection part 12 detects a pitch Pin of an input voice signal Vin supplied from a voice input part 61. An envelope detection part 13 detects a spectrum envelope of the input voice signal Vin. A spectrum acquisition means 30 acquires a frequency spectrum of the voices for conversion including a plurality of voices uttered in parallel. A pitch conversion part 21 varies each peak frequency of the frequency spectrum acquired by the spectrum acquisition means 30 according to the pitches Pin. An envelope adjustment part 22 adjusts the spectrum envelope of the frequency spectrum having been processed by the pitch conversion part 21 so that the envelope almost match with the spectrum envelope detected by the envelope detection part 13. A voice production means 40 produces an output voice signal Vnew from the frequency spectrum having been adjusted by the envelope adjustment part 22. COPYRIGHT: (C)2006,JPO&NCIPI
