A Japanese sentence-internal “bunsetsu”(minimal syntactic phrase comprising a content word possibly followed by particles) often has an intonational movement in the final syllable. This study investigates this type of sentence-internal intonation based on the conversational data and listening tests using resynthesized speech. Among the types of intonation used at the end of bunsetsu, (1) emphatic rise( step rise),( 2) rise-fall, and( 3) prolonged neutral intonation appeared most frequently in conversations. The listening tests showed that the rise-fall has a function of request for attention and simultaneously serves as an indicator of the current status in speech planning. Examination of the conversational data suggested that the choice of the intonation type also depends on presence/absence of an interjection particle (ne or sa), depth of the syntactic and discourse boundary, formality of speech situation, and the speaker’s attributes( generation and gender).
