We developed a CALL (computer-aided language learning) system for teaching the pronunciation of Japanese long vowels, the mora nasal and mora obstruents to non-native speakers of Japanese. Long vowels and short vowels are spectrally almost identical but their phone durations differ significantly. Similar conditions exist between mora nasals and non-mora(More)
We h a v e built a prototype Automatic Dialogue Sum-marizer (ADS) | a real{time system that automatically generates simple summaries of completely spontaneous human{human spoken dialogues without the machine interrupting the natural ow o f conversation. Two dialogue participants (client and clerk) discuss conference room reservations (CRR) in Japanese, and(More)
We examined pitch patterns within and across intonational phrases of Japanese read aloud by native and non-native (Mandarin Chinese) speakers. Japanese speakers change pitch ranges for each intonational phrase. The relative pitch ranges of neighboring intonational phrases indicate which intonational phrase belongs to which intonational phrase group. Chinese(More)
We compared pitch patterns of Japanese intonational phrases spoken by a native speaker of Chinese. Several types of pitch errors were distinguished according to pitch contour shapes within and across intonational phrases. These shapes differ categorically from one another—for instance, the learner uses flat contours while the native uses hump-like contours.(More)
We used a command-response additive F 0 model to analyze F 0 patterns of Japanese spoken by native speakers of Mandarin Chinese. Compared to native speakers of Japanese, we found that Chinese speakers exhibit the following characteristics: (a) higher pitch, (b) more phrases, (c) bunsetsu decomposition, and (d) utterance-final plunging. These characteristics(More)
