| Research Abstract |
This study investigated speech rhythm produced by native and non-native Japanese speakers, using durational variables which are used to categorize languages by their speech rhythm. We collected Japanese read speech data of native speakers of Chinese, Vietnamese, Korean and French. We have accumulated 343 Japanese words containing tokushu-haku, which are geminate consonants, moraic nasals, long vowels, /CjV/ sequences, and devoiced vowels. The speakers' Japanese utterances were segmented and analyzed by durational variables: (1) durational ratios, (2) standard deviation, (3) coefficient of variation, (4) pairwise variability index, and (5) average of normalized voice onset asynchrony.
The analyses of these durational variables showed that individual variables were not effective enough to differentiate between native and non-native Japanese speakers' speech rhythm. At least two or often more than three variables were required to discriminate between the native and non-native groups.
