Applying voice conversion to concatenative singing-voice synthesis

Abstract

This work address the application of Voice Conversion to singing-voice. The GMM-based approach was applied to VOCALOID, a concatenative singing synthesizer, to perform singer timbre conversion. The conversion framework was applied to full-quality singing databases, achieving a satisfactory conversion effect on the synthesized utterances. We report in this paper the results of our experimentation focused to study the spectral conversion performance when applied to specific pitch-range data.
