A system for singing synthesis provided herein is capable of generating singing by integrating into one singing a plurality of vocals sung by a singer a plurality of times or vocals of which parts that he/she does not like are sung again. The music audio signal playback section 7 plays back the music audio signal from a signal portion or its immediately preceding signal portion of the music audio signal (background signal) corresponding to a character in the lyrics when the character displayed on the display screen 6 is selected by a character selecting section 9. The estimation and analysis data storing section 13 automatically aligns the lyrics with the vocal, decomposes the vocal into three elements, pitch, power, and timber, and stores them. The data selecting section 17 allows the user to select pitch, power, and timbre data for respective time periods of phonemes. The data editing section 19 modifies the time periods of the pitch, power, and timbre data in alignment with the modified time periods of the phonemes.
