PROBLEM TO BE SOLVED: To improve detection accuracy for the intermusic space of a plurality of music pieces based on an analog voice signal.;SOLUTION: Voice data generated by converting the analog voice signal of music in which the intermusic space of a plurality of music piece is constituted of a nosound part into a digital signal are subjected to noise removal to generate noise removed voice data D11. Based on a part in which the signal level of the generated noise removed voice data D11 is lower than a predetermined level threshold, an intermusic space estimated as the intermusic space of a plurality of music pieces are detected, and the intermusic space is specified based on the intermusic specifying information of the detected estimated intermusic spaces. Thus, the intermusic space constitued of music nosound part based on the analog voice signal is accurately detected by suppressing a noice influence as much as possible, and detection accuracy for the intermusic space of a plurality of music pieces based on the analog voice signal is improved.;COPYRIGHT: (C)2005,JPO&NCIPI
