项目摘要

The aim of the present study is to clarify the effects of the insertion of an intra-sentential pause on the temporal organization of an utterance.A Japanese test sentence, with a possible pause location at a major syntactic boundary roughly in the middle of the sentence, was produced by native speakers under two contrasting conditions, i.e.with and without an intra-sentential pause, and the durational properties of the utterances were analyzed acoustically.The results indicated that the insertion of an intra-sentential pause has a major effect on the immediately-prepausal region of an utterance in the form of so-called 'prepausal lengthening'. It was also indicated that an intra-sentential pause brings about minor changes in the temporal organization of the remaining parts of the utterance, although the exact location and the extent of these minor changes varied from speaker to speaker.Pre-pausal lengthening was examined in detail, and it was found that, in Japanese, it occurs primarily in the mora that immediately precedes a pause. Interestingly it was also found that, in some speakers, pre-pausal lengthening extends over two moras. The lengthening of an additional mora was, however, substantially smaller than that of the immediately-prepausal mora. The results also revealed that the vowels bear the major burden of lengthening in Japanese, especialy as concerns the immediately pre-pausa mora.

本研究的目的是阐明插入句内停顿对话语时间组织的影响。一个日语测试句子，其可能的停顿位置大致在句子中间的主要句法边界，由母语者在两种对比条件下产生，即有和没有句内停顿，并对话语的持续时间特性进行声学分析。结果表明：插入句内停顿对话语的前停顿区域具有重大影响，即所谓的“停顿前延长”。还指出，句内停顿会导致话语其余部分的时间组织发生微小变化，尽管这些微小变化的确切位置和程度因说话者而异。对停顿前延长进行了详细研究，结果发现，在日语中，它主要发生在停顿之前的短节中。有趣的是，我们还发现，在一些说话者中，停顿前的延长延伸到两个音节。然而，额外的莫拉的延长远远小于立即前的莫拉的长度。结果还显示，元音在日语中承担着延长的主要负担，特别是在涉及紧邻的前暂停音节时。
