ABSTRACT:
Voice synthesis unit data stored in a phoneme database10is selected by a voice synthesis unit selector12in accordance with MIDI information stored in a performance data storage unit11. Characteristic parameters are derived from the selected voice synthesis unit data. A characteristic parameter correction unit21corrects the characteristic parameters based on pitch information, etc. A spectrum envelope generating unit23generates a spectrum envelope in accordance with the corrected characteristic parameter. A timbre transformation unit25changes timbre by correcting the characteristic parameters in accordance with timbre transformation parameters in a time axis. Timbres in the same song position can be transformed into different arbitrary timbres respectively; therefore, the synthesized singing voice will be rich in variety and reality.
