| Research Abstract |
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.
