在第二語言習得領域中,以台灣日語學習者為研究對象的發音研究普遍認識到,長/短母音的發音與日語音韻對立的特性密切相關。然而,儘管這些研究強調學習者要正確產出長/短母音的話,必須學會掌控母音的長度,卻鮮少有系統性地探討在不同語音環境下,學習者如何實現長/短母音發音的實證研究。要實現日語發音的等拍特性,學習者在產出長/短母音發音時,必須精確掌握適當的母音長度。因此,有必要透過量化分析來闡明學習者的長/短母音發音的特徵,並了解影響學習者的長/短母音發音的因素。 本研究以39位台灣日語學習者為受試者,探討影響學習者的長/短母音發音的因素。研究結果顯示,相較於長母音的發音錯誤,台灣日語學習者更容易犯短母音的長音化錯誤。此外,透過長/短母音的同定評價實驗,發現影響學習者掌握母音長度的關鍵因素是音節位置。同時也對其他可能影響母音長度的因素,諸如重音型態、半母音的存在、以及音節結構進行了深入分析。 In the field of second language acquisition, research on the pronunciation of Taiwanese Japanese learners generally acknowledges the characteristics of Japanese phonological opposition associated with the pronunciation of long/short vowels. However, despite these studies emphasizing the necessity for learners to accurately produce long/short vowels, there is a noticeable lack of empirical research on how learners achieve long/short vowel pronunciation m different phonetic environments. To achieve the mora-timed rhythm of Japanese pronunciation, learners must master the appropriate vowel duration when producing long/short vowels. Therefore, it is necessary to clarify the characteristics of learners' long/short vowel pronunciation through quantitative analysis and comprehend the factors influencing learners' long/short vowel pronunciation. This research, with the participation of 39 Taiwanese learners of Japanese, examines the factors that impact the pronunciation of long and short vowels by Taiwanese Japanese learners. The results indicate that Taiwanese Japanese learners are more prone to errors in short vowels as compared to long vowels. Furthermore, the long/short vowel evaluation experiment showed that syllable position is a crucial factor in affecting vowel length production. The research also investigated various factors that might affect vowel length production, including accent type, semivowels, and syllable structure. |
