本研究考察了三种语音类别不同的语言中语速对顿音产生的影响。本文研究了CV(C)单词在独立和上下文中慢速和快速语速下产生的初始唇部和肺泡停止辅音的起音时间（VOT）分布和平均VOT值。结果显示，在三种语言中，短滞后类别并没有随着说话速度的变化而变化，尽管长滞后（泰语和英语）和前置发音（泰语和法语）顿音的VOT值受到说话速度变化的影响。然而，在快语速条件下，长滞后和预发音类别向短滞后VOT值的转变导致发音类别之间的重叠很少。讨论了这些结果对语音范畴性质的影响。(C) 1997学术出版社有限公司
This study investigated the effect of speaking rate on stop consonant production in three languages which have different phonetic categories of voicing. Voice-onset time (VOT) distributions and mean VOT values were examined for initial labial and alveolar stop consonants produced in CV(C) words in isolation and in context at both slow and fast rates of speech. Results revealed that the short lag category did not change as a function of speaking rate in any of the three languages examined, although VOT values for long lag (Thai and English) and pre-voiced (Thai and French) stop consonants were affected by changes in speaking rate. However, the shift of the long lag and pre-voiced categories toward the short lag VOT values in the fast rate condition resulted in little overlap between voicing categories. Implications of these results for the nature of phonetic categories are discussed. (C) 1997 Academic Press Limited
