| Research Abstract |
This study examined the effect of insertion of an intra-sentential pause on the temporal organization of the utterances both preceding and following the pause. A Japanese test sentence was produced with and without an intra-sentential pause by ten native speakers. Speech data were analyzed by examining the articulation rate ratio (ARR), i.e. the ratio of the articulation rate in the "pause condition" to that in the "no pause condition", of pre-pausal and post-pausal utterances.
Major results can be summarized as follows :
(1) The intended insertion of an intra-sentential pause resulted in a substantial drop in the articulation rate in the utterance region immediately preceding the pause. The articulation rate decreased by about 20%-30% compared with a production without an intra-sentence pause. The finding confirmed the presence of pre-pausal lengthening in Japanese
(2) Intra-sentential pause insertion also changed the articulation rate in other parts of the utterance. The magnitude of the articulation rate change was small (approximately 5% increase or decrease) compared with the pre-pausal drop. This type of articulation rate change tended to be realized either as an increase or a decrease depending on the speaker.
The present study was carried out in an attempt to find out if the effect of an intra-sentential pause was confined primarily to the prepausal region or if it extended over to other parts of the utterance as well. The results indicated that an intra-sentential pause has two characteristically different effects on the articulation of the utterance, local and global. The local effect manifested itself as the so-called prepausal lengthening, I.e. as a substantial drop in the articulation rate immediately before the pause, while the global effect manifested itself as a smaller increase/decrease in the articulation rate that extended both pre-pausally and post-pausally to the remaining parts of the utterance.
