| Research Abstract |
Short Japanese utterances were analyzed acoustically to investigate the temporal fluctuation of syntactic phrases. With reference to the average duration of the phrase-only utterances, duration of each phrase within the sentence utterance was analyzed. Though Japanese is said to have a mora-timed rhythm with little fluctuation of mora duration, duration of a sentence-final phrase or a phrase just before a deep syntactic boundary was relatively longer. The phrase just before a prolonged phrase was relatively shorter.
Duration of a musical bar was also acoustically analyzed. Pieces of classical music with quick tempo were investigated. The results also showed the tendency of "Final-lengthening" at the end of a musical phrase, which normally consists of four bars. However, the duration of a bar just before the prolonged one was often found significantly short. Within the general four-bar phrase structure, a "Short-Long-Short-Long" pattern was often observed.
