The objective of this study is to examine acoustically the effects of an intra-sentential pause on neighboring utterances. A Japanese test sentence was read by 10 native speakers in two contrasting ways, i.e., with and without an intra-sentential pause. The effects of pause insertion were analyzed on the basis of the measurements of mora duration, vowel formant frequency, and fundamental frequency. The results showed that all three parameters were affected by pause insertion. More interestingly, the pausal effect on the mora duration and vowel formant frequency was basically limited to a single mora whereas the effect on the fundamental frequency extended over multiple moras.
