최적성이론에 의한 중국인 한국어 학습자의 /n.l/ 실현 양상 분석

초록

This study compared the pronunciation patterns of /n.l/ in Korean by native Korean speakers and Chinese learners, and explained the differences using Optimality Theory. The participants of this study included 10 native Korean speakers and 20 Chinese Korean learners (10 intermediate, 10 advanced). The experiment involved presenting sentences containing Korean words with /n.l/ to the participants and having them read them aloud. The results showed that native Korean speakers realized /n.l/ as a nasalization in disyllabic words and as a lateralization in trisyllabic words. Intermediate Chinese learners mostly pronounced /n.l/ according to the spelling, while advanced learners realized it as a lateralization. Furthermore, differences in the realization patterns of /n.l/ were observed within the group of Chinese learners based on their proficiency levels. The realization patterns of intermediate learners differed significantly from those of native Korean speakers, Realization patterns of advanced learners were similar to nativer Korean speakers in disyllabic words, however, they differed significantly in trisyllabic words. These changes were explained in terms of constraint rankings, as follows. - Chinese intermediate learners of Korean constraint ranking: Syllcon, Align-L, Align-R ≫ Indent(lat) ≫ Indent(nas) - Chinese advanced learners of Korean constraint ranking: Syllcon ≫ Align-L, Align-R ≫ Indent(lat) ≫ Indent(nas) - Korean speakers constraint ranking: Syllcon ≫ Align-L, Align-R ≫ Ons-cond ≫ Indent(lat) ≫ Indent(nas)
