韓国人日本語学習者における日本語のザ行 音とジャ行音の習得について ―聞き取り調査を通して―

Abstract

This paper empirically investigates and analyzes the acquisition of the Japanese “Za-gyō-sounds” (za, z u, and zo) and “Ja-gyō-sounds” (ja, ju, and jo) by Korean learners. There are four research questions addressed here: (1) Do Za-gyō-sounds and Ja-gyō-sounds differ in ho w they are heard by Korean learners depending on their Japanese proficiency level?, (2) is there is a signifi cant difference among the Za-gyō-sounds (za, zu, and zo) as heard by Korean speakers?, (3) is there is a si gnificant difference among the Ja-gyō-sounds ( ja, ju, and jo) as heard by Korean speakers?, and (4) is ther e is a difference between the Za-gyō-sounds and Ja-gyō-sounds as heard by Korean speakers? The following results were obtained: (1) There was no difference in the hearing ability between Korean learners of Japanese at the beginner and intermediate levels, (2) there was a significant difference among t he Za-gyō-sounds (za, zu, and zo), (3) there was also a significant difference among the Ja-gyō-sounds (ja, ju, and jo), and (4) there was no statistically significant difference between the Za-gyō-sounds and Ja-gyō- sounds but there were significant differences between zu and ju and between zo and jo. From these results, I have empirically demonstrated that the acquisition of Japanese Za-gyō-sounds and Ja-gyō-sounds is different to those predicted in the contrastive linguistic analysis of Korean and Japanese.
