| Research Abstract |
日本語・北京語・上海語・韓国語について、MRIやEGGなどの分析尺度で、東アジア言語の破裂音の相互類似性について分析した。
MRIの結果、日本語の有声破裂音及び韓国語の語中の平音には、声帯振動時の開口度や持続時間に類似性が観察された。また、韓国語の濃音、北京語の無声無気音、日本語の無声破裂音に、声帯振動を早く終了させて声帯の動きを停止させる傾向が観察された。EGG分析においても、日本語、上海語の有声破裂音、韓国語の平音に、声帯接触による振動が見られるなど類似性がうかがわれた。
It is often difficult for East-Asian learners of Japanese to acquire perception and pronunciation of Japanese plosives. Notably, the voiceless Japanese plosives are misheard as voiced Japanese plosives by Chinese and Korean L1 learners of Japanese varying according to the position of the plosive. From the results of study of 2nd language acquisition of plosives it is thought that the Japanese voiceless plosive holds the key to why East-Asian learners of Japanese mishear the voiced and voiceless plosives in Japanese.
Therefore, the study was based on gathering experimental fMRI data concerning the voiceless Japanese plosives, the voiceless un-aspirated Chinese plosives, and the forced Korean plosives. These were then compared to the characteristic of the plosive of each language. Furthermore, the study revealed the resemblances between Japanese and the other languages that cause language interference while learning Japanese as an L2. They were then compared by examining the characteristics of the respective plosives.
