Acappella Synthesis Demonstrations using RWC Music Database

A series of demonstrations of synthesized acappella songsbased on an auditory morphing using STRAIGHT [5] willbe presented. Singing voice data for morphing were extracted from the RWCmusic database of musical instrument sound. Discussions on a new extension of the morphing procedure to deal with vibrato will be introduced basedon the statistical analysis of the database and its effect onsynthesized acappella will also be demonstrated.
