Three categorization experiments investigated whether the speaking rate of a preceding sentence influences durational cues to the perception of suprasegmental lexical-stress patterns. Dutch two-syllable word fragments had to be judged as coming from one of two longer words that matched the fragment segmentally but differed in lexical stress placement. Word pairs contrasted primary stress on either the first versus the second syllable or the first versus the third syllable. Duration of the initial or the second syllable of the fragments and rate of the preceding context (fast vs. slow) were manipulated. Listeners used speaking rate to decide about the degree of stress on initial syllables whether the syllables' absolute durations were informative about stress (Experiment Ia) or not (Experiment Ib). Rate effects on the second syllable were visible only when the initial syllable was ambiguous in duration with respect to the preceding rate context (Experiment 2). Absolute second syllable durations contributed little to stress perception (Experiment 3). These results suggest that speaking rate is used to disambiguate words and that rate-modulated stress cues are more important on initial than noninitial syllables. Speaking rate affects perception of suprasegmental information.
三项分类实验研究了前一个句子的语速是否会影响对超音段词汇重音模式感知的时长线索。荷兰语双音节单词片段必须被判断为来自两个较长单词中的一个，这两个较长单词在片段上与该片段匹配，但在词汇重音位置上有所不同。单词对在第一个音节与第二个音节或第一个音节与第三个音节上的主重音形成对比。对片段的初始音节或第二个音节的时长以及前一个语境的语速（快与慢）进行了操控。听众利用语速来判断初始音节的重音程度，无论音节的绝对时长是否能提供有关重音的信息（实验Ia）或不能提供有关重音的信息（实验Ib）。只有当初始音节在时长上相对于之前的语速语境不明确时，语速对第二个音节的影响才可见（实验2）。第二个音节的绝对时长对重音感知的贡献很小（实验3）。这些结果表明，语速被用来消除单词的歧义，并且语速调制的重音线索在初始音节上比在非初始音节上更重要。语速会影响对超音段信息的感知。
