タイ語母語話者による日本語促音・非促音の誤発声

抄録

To clarify the characteristics of Thai speakers’ mispronunciation of Japanese singleton and geminate stops, durations of the closure and the preceding and following consonant-vowel segments were analyzed. Compared with native Japanese speakers, Thai speakers mispronounced singleton stops with a longer closure and a shorter preceding consonant-vowel segment. They also mispronounced geminate stops with a shorter closure and a longer following consonant-vowel segment. These results are consistent with a previous study of Korean and Taiwanese Mandarin speakers, suggesting that non-native speakers commonly mispronounce Japanese singleton and geminate stops with inadequate durations of a closure segment and preceding and following consonant-vowel segments.
