朗讀文章時的促音發音問題─以台灣人初級日語學習者為研究對象─

本研究以促音語為研究題材，探討台灣人初級日語學習者在朗讀文章時的促音發音問題。利用語音分析軟體測量各分節音的長度，客觀地掌握學習者促音發音的語音時長特徵。語音分析的結果可歸納為以下3點。（1）學習者所發的促音語中，促音的持阻時間較日本人為短。因此常出現應該是有促音卻聽不出促音的存在，以及無法斷定是否有促音存在的問題。（2）一部分的學習者傾向於將促音前方的母音長度拖長，產生所謂長音化的現象。由於在沒有促音的其他分節音位置，並沒有明顯觀察到長音化現象。因此我們認為這是因促音的存在而引起的發音問題。（3）由於朗讀文章時，出現許多單獨發促音語時不存在的問題。由此可知，話語型態的不同，會對促音的發音產生不同的影響。

The acquisition of Japanese geminate consonants is difficult for most Taiwanese Japanese learners. To examine how Taiwanese beginning learners pronounce Japanese words with geminate consonants, an acoustic analysis of Taiwanese beginning learner's speech data is collected and analyzed. The results are summarized as follows: 1) Closure duration of Japanese geminate consonants produced by Taiwanese beginning learners tends to be too short. So listeners mistook these geminate consonants as non-geminate ones or they couldn't distinguish geminate consonants from non-geminate consonants. 2) Taiwanese beginning learners tend to pronounce the vowel sounds before geminate consonants too long. So listeners mistook these vowels to be long vowels. 3) Speech style seems to influence Taiwanese beginning learners' pronunciation of geminate consonants.
