제2언어 학습 과정에 나타난 한국어 음운 지각과 산출 -중국인 학습자의 중첨자음과 단자음 변별을 중심으로-

초록

The Journal of Studies in Language 30.4, 787-805. This study examined adult L2 learners’ perception and production of non-native speech contrasts. The word-medial singleton/geminate contrasts in Korean sonorant consonants such as /m, n, l/ are differentiated acoustically by temporal parameters, (e.g., duration of closure for medial consonants, duration of preceding vowel). The participants in the present study were two groups of Korean-learning Chinese who differed according to their degrees of experience in Korean(beginners and intermediate learners). Both groups showed better discrimination in perception than in production of the singleton/geminate consonants. The intermediate learners’ discrimination rate in production was obviously higher than the beginners’, whereas there was no significant difference in perception between the two groups. The acoustic analysis clearly indicate that the participants who failed to discriminate singleton/geminate consonants in perception also produced the geminate consonants with significantly longer closure durations than the singleton consonants. This result suggests that they produce such sounds under conscious (i.e. nonautomatic) control. Therefore, L2 learners’ differential pronunciation of L2 contrasts does not necessarily mean that they have established separate phonetic categories for L2 sounds. (Hanyang University)
