特殊拍之促音對日語學習者而言經常被認為不易學習。然針對台灣的學習者,似乎少見以篇章朗讀的調查方法進行實證性研究。本研究使用日文語言課題,對兩名日語母語話者與十名台灣學習者,測量他們的促音持阻時長,研究結果得知(1)學習者整體的日語學習時數長短與促音習得無有意相關,換言之學習經歷長者未必比經歷短者,促音發音好(2)確定促音的持阻時長在語辭間對學習者的難度不等。最後略言教學方面的建議事項。|This study used an oral reading task in Japanese and measured the durations of double consonants produced by 2 native speakers and 10 Taiwanese learners of Japanese. The results showed that (1) the learner ability level did not correlate with the level of acquisition of double consonant duration, and (2) the double consonant durations for some words were easier than those for others. Pedagogical implications are briefly discussed.
