Pitch movements at the boundaries of sentence-medial and final phrases in Japanese can provide a cue to the speaker's intention. For example, the phrase /Nagano-de/ 'in Nagano' can be uttered with different rising and/or falling pitch movements on the the final mora /de/ to convey meanings such as clarification, incredulity, prominence in the discourse, insistence, etc. The identification of these movements is important not only for spoken language understanding systems, but also for natural-sounding speech synthesis. The current study examines F0 shape, height, and alignment characteristics of four distinct sentence-medial boundary rises. We compare these types with accented and focused unaccented words containing identical phonetic segments, and discuss a number of different possible phonological analyses of the pitch movements.
