本硏究では、調音位置による韓國人初級學習者の日本語破裂音の特徵を音響音聲學的に分析した。韓國語と日本語子音の構造は互いに異なる體系を持っている。このような異なる言語的特殊性によって兩國の言語には違いが存在し、母語にない音韻體系を發音する學習者には相當な負擔となる。 したがって、本硏究では韓國人初級學習者が持つ日本語破裂音の特徵における旣存の破裂音硏究を補完し、調音位置による語頭破裂音と語中破裂音を比較した。また、語中破裂音の場合、日本語の發音が來られる環境を考慮し、母音後、中子音後、發音後に分けて結果を導き出した。 分析の結果、韓國人の初級學習者の日本語破裂音發音に對する音響音聲學的端緖として作用する基本周波數、聲帶振動の開始時間、閉鎖持續時間の特徵を確認することができた。 旣存の硏究では無意味な單語、日本人破裂音の特徵に注目されてきたが、本硏究では韓國人初級學習者との比較を通じて考察を行ったものであるため、日本語音聲敎育現場に提供したい。今後は、對話體における破裂音特徵を考察していきたい。

In this study, we analyzed phonetically the characteristics of Japanese plosive consonants which are pronounced according to the articulation position of Korean learners. The structures of Korean and Japanese consonants have different systems. Due to these linguistic features, there is a difference in the language between the two countries, which is a considerable burden for learners who pronounce the phonological system rather than their native language. Therefore, in this study, the characteristics of the Japanese plosive consonants of the beginner learners were compared between the plosive consonant occurred in the first and second syllable of word according to the articulation positions. Also, considering the plosive consonants used in Japanese sentences, the three conditions which are after a vowel, after a double consonant, and after a nasal occurrence in the second syllable through acoustic point of view, are experimented. Through this study, it was confirmed that the characteristics of the fundamental frequency, the voiced onset time, and the duration time of close, which act as acoustical cues for the pronunciation of the Japanese plosive consonants of Korean learners. In contrast to analyzing the characteristics of Japanese plosive consonants in the meaningless words of previous studies, this study aims to provide a basis for Japanese language education by comparing the characteristics of beginner learner who speak words of practical sentences.
