Abstract
Herein provided is a system for singing synthesis capable of reflecting not only pitch and dynamics changes but also timbre changes of a user's singing. A spectral transform surface generating sectiontemporally concatenates all the spectral transform curves estimated by a second spectral transform curve estimating sectionto define a spectral transform surface. A synthesized audio signal generating sectiongenerates a transform spectral envelope at each instant of time by scaling a reference spectral envelope based on the spectral transform surface. Then, the synthesized audio signal generating sectiongenerates an audio signal of a synthesized singing voice reflecting timbre changes of an input singing voice, based on the transform spectral envelope and a fundamental frequency contained in a reference singing voice source data.
