作者的前期研究表明，命令-反应模型对普通话的F0曲线有很好的应用，可以用来提取参数，也可以用来推导语音合成的规则。本文描述了六位本族语者在三种语速下的F0曲线的分析结果，以考察语速和说话者差异的影响。文中还描述了在三种语音速率下的音节持续时间的分析结果。这些结果被用来导出普通话语音合成中F0轮廓生成的规则和参数的量化水平。特别是，它表明，音节持续时间的三级量化与F0轮廓参数的规则相结合时，韵律的自然性是足够的。
Previous studies by the authors have shown that the command-response model applies quite well to F 0 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 F 0 contours of utterances by 6 native speakers at three speech rates, conducted to examine the effects of speech rate and speakerdifferences. It also describes results ofanalysis of syllable durations at the three speech rates. These results are then applied toderive rulesandquantizationlevels ofparametersfor F 0 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 F 0 contour parameters.
