摘要通过一个产出实验和一个知觉实验，研究了语速对意大利语单辅音/双辅音对比的影响。声学分析进行了唇和牙齿的单辅音和双辅音在孤立的话，并在一个单独的背景下，在一个缓慢和快速的讲话。关闭持续时间被发现区分两类辅音在给定的说话速率。对于一个人来说，在一个快速的讲话速度的双辅音的关闭时长的分布是相同的单辅音的关闭时长的分布在隔离。然而，反映两个持续时间之间的关系，辅音持续时间和前面的元音持续时间之间的比率，区分单音节和双音节内和跨说话率的措施。知觉实验测试是否操纵辅音元音比例会导致知觉转移。结果表明，改变比例确实会影响双生子/单胞胎区别的感知。然而，这些影响在不同的听众之间差异很大。两者合计，这些研究结果提供了支持的观点，即有稳定的声学特性对应的语音功能，即使一种类型的时间信息，关闭持续时间，在很大程度上受说话速率的变化，高阶关系的措施保持不变。
Abstract A production and a perception experiment were conducted to investigate the effect of speaking rate on the singleton/geminate consonant contrast in Italian. Acoustic analyses were performed of labial and dental singleton and geminate consonants produced in words spoken in isolation and in a sentential context at both a slow and a fast rate of speech. Closure duration was found to discriminate between the two categories of consonants within a given speaking rate. For one speaker, at a fast speaking rate the distribution of closure duration of geminate consonants was identical to the distribution of closure duration of singleton consonants produced in isolation. However, a measure reflecting the relation between two durations, the ratio between consonant duration and preceding vowel duration, discriminated between singletons and geminates both within and across speaking rates. The perception experiment tested whether manipulation of the consonant to vowel ratio would result in perceptual shifts. Results indicated that changing the ratio did affect perception of the geminate/singleton distinction. However, these effects varied greatly across listeners. Taken together, these findings provide support for the view that there are stable acoustic properties corresponding to phonetic features in that even though one type of temporal information, closure duration, is greatly affected by changes in speaking rate, a higher-order relational measure remains constant.
