Tone of voice changes reflect singing voice synthesis method and tone of voice changes reflect singing voice synthesis system

摘要

To provide a tone of voice changes reflect singing voice synthesis system, which can be reflected in the singing voice synthesis singing not only changes in the volume and pitch of the user singing, vocal sound to change. Spectral modification surface generation unit 119 generates the spectral modification curved to match the spectral deformation curve deformation curve spectrum estimation section 117 of the second estimated. At each time, the synthetic acoustic signal generator 121 generates a deformed spectrum envelope by deforming the reference spectrum envelope based on the spectral deformation curved surface. And to generate the acoustic signal of the singing voice that has been synthesized to reflect the change in the tone of voice of the input singing voice based on the fundamental frequency to be included in the reference singing sound source data and deformation spectrum envelope.
