本文讨论了汉语普通话中语速和韵律单位之间相互作用的证据。对2种不同语速的普通话语音数据进行了边界和韵律单位标记，并进一步分析了每个韵律水平上的时长模式。每个韵律水平表现出的持续时间调整的模式，可以占所使用的模型的两个语音速率。这些模式的持续时间的调整显然是系统的，这表明如何每个韵律水平可能会相互作用，并在一定程度上管理时间内的单位分布。我们的研究结果表明，虽然表面上看，语速可能是一个全球性的现象，在整个语音流，它实际上是非常完整的韵律组织的一部分，由每个韵律水平的约束。简而言之，时长调整不是一种一刀切的现象，而是在语音产生的各个韵律层次上系统地进行的。因此，韵律单位和时间分布之间的相互作用是可预测的。我们相信，这些发现是一个进步，在理解时间组织和分布的语音流以及语音韵律一般，并应直接适用于预测语音韵律的无限TTS特别。
This paper discusses evidence of interaction found between speech rate and prosody units in Mandarin Chinese speech. Mandarin speech data of 2 different speech rates that had been previously labeled for perceived boundaries and prosody units were further analyzed for duration patterns at each prosodic level. Each prosody level demonstrated patterns of duration adjustment for both speech rates that could be accounted for by the model used. These patterns of duration adjustments are clearly systematic, suggesting how each prosody levels may interact and to an extent govern the temporal distribution of units within. Our findings demonstrate that though speech rate may appear to be a global phenomenon across speech flow on the surface, it in fact is very much an in integrated part of prosody organization constrained by each prosody level. To put simply, duration adjustment is being made systematically at each prosody level during speech production instead of just an across-the-board phenomenon. As a result, interactions between prosody units and temporal distribution are predictable. We believe these findings are a step forward in understanding temporal organization and distribution of speech flow as well as speech prosody in general, and should be directly applicable to predicting speech prosody of unlimited TTS in particular.
