Sixth International Conference on Spoken Language Processing
Previous studies by the authors have shown that the commandresponse model applies quite well to F0 contours of Standard Chinese, and can be used to extract parameters as well as to derive rules for speech synthesis. The present paper describes results of analysis of F0 contours of utterances by 6 native speakers at three speech rates, conducted to examine the effects of speech rate and speaker differences. It also describes results of analysis of syllable durations at the three speech rates. These results are then applied to derive rules and quantization levels of parameters for F0 contour generation in speech synthesis of Standard Chinese. In particular, it shows that a three-level quantization of syllable duration is sufficient for the naturalness of prosody when combined with rules for F0 contour parameters.
