APPARATUS, METHOD, AND PROGRAM FOR SINGING SYNTHESIS

摘要

PROBLEM TO BE SOLVED: To convert one singing part into parts of arbitrary different voice quality and to synthesize a singing voice with rich variation and reality.

SOLUTION: According to MIDI information held in a playing data holding part 11, a voice phoneme selection part 12 selects voice phoneme data stored in a vocal sound database 10. A feature parameter is selected from the selected voice phoneme data. A feature parameter correction part 21 corrects the feature parameter according to pitch information etc. A spectrum envelope generation part 23 generates a spectrum envelope according to the feature parameter having been corrected by the feature parameter correction part 21. A voice quality conversion part 25 corrects the feature parameter according to voice quality conversion parameters to change the voice quality and also change the voice quality conversion parameters with time.
