文献描述了两种类型的持续时间的影响音节的话语。它们是在许多句法边界之前延长音节（“域末延长”）和在非重读音节之后缩短重读音节（“音步缩短”）。在本研究中，我们研究了这两种计时现象之间的关系。特别是，我们研究的可能性，句法边界在延长发生划定域在脚水平缩短实现。为了验证这一假设，我们改变了音节结构的韵律脚跨越词的边界，要么符合名词短语（NP）/动词短语（VP）的边界或没有。在这些条件下的重读音节持续时间的比较未能证实这一假设。相反，非重读音节缩短了重读音节相同的持续时间跨越NP/VP边界内的一个短语。我们的研究结果表明，这两个影响是独立的。发现脚水平缩短跨度最终延长句法边界进行了讨论的缩短效应的理论。
The literature describes two kinds of durational influence on the syllables of an utterance. They are a lengthening of syllables before many syntactic boundaries (‘domain-final lengthening’) and a shortening of stressed syllables followed by unstressed syllables (‘foot-level shortening’). In the present study we examined the relationship between these two timing phenomena. In particular, we examined the possibility that syntactic boundaries at which lengthening occurs delimit the domains over which foot-level shortening is realized. To test this hypothesis, we varied the syllabic structure of metrical feet spanning word boundaries that either coincided with a noun-phrase (NP)/verb-phrase (VP) boundary or did not. Comparison of stressed syllable durations in these conditions failed to confirm the hypothesis. Instead, unstressed syllables shortened stressed syllables by the same duration across an NP/VP boundary as within a phrase. Our findings suggest that the two effects are independent. The finding that foot-level shortening spans finally lengthened syntactic boundaries is discussed in relation to theories of the shortening effect.
