A study on the pitch pattern of a singing voice synthesis system based on the cepstral method

We synthesize singing voice by rule based on cepstral method. Higher accuracy of analysis and synthesis is required to synthesize singing voice, comparing to rule-based speech synthesis. In this paper, we propose a method of analysis and synthesis with high accuracy. Also, we express pitch patterns minutely by curves that close to natural pitch by using this method. We apply Fujisaki model and add vibrato to the pitch pattern.
