我们提出了韵律事件时间特性的实验结果，提供了证据，证明样本的积累隐式地定义了韵律产生中的感知目标区域。我们认为片段和音节持续时间的 z 分数是这些区域的相关感知维度。为了支持这一假设，我们提出了实验结果，证实不同韵律背景下的片段和音节的实现显示出显着不同的 z 分数分布。进一步的实验表明，音节 z 分数和相应片段的 z 分数之间的关系对于不频繁音节明显强于频繁音节。我们声称这是因为不常见的音节必须由较小的单元组装而成，因为它们没有足够的范例来表示来建立音节级目标区域。
We present results from experiments on the temporal properties of prosodic events, providing evidence that accumulations of exemplars implicitly define perceptual target regions in prosody production. We argue that z-scores of segment and syllable durations are the relevant perceptual dimension of these regions. To support this hypothesis, we present experimental results confirming that realizations of segments and syllables in different prosodic contexts show significantly different z-score distributions. Further experiments show that the relationship between syllable z-scores and the z-scores of the corresponding segments is significantly stronger for infrequent than for frequent syllables. We claim that this is due to the fact that infrequent syllables have to be assembled from smaller units because they are not represented by enough exemplars to establish a syllable-level target region.
