제2외국어로서 영어와 한국어 폐쇄음 산출과 인지 연구

This study examines how L1 Korean learners of L2 English and L1 English learners of L2 Korean produce L2 stops in terms of voice onset time (VOT) and fundamental frequency (F0) and how they perceive L2 stops. The study also examines how the level of L2 proficiency functions as a critical factor in determining the L1-to-L2 influence. Two findings were derived from production experiments. First, the primary acoustic cues of L1 stops are negatively transferred to the production of L2 stops in L2 beginners. Second, advanced L2 learners acquire the primary cues of L2 stops. These results indicate that the acquisition of L2 stops is regulated by the different priority order of VOT and F0 between L1 and L2 stops and learners' L2 proficiency. Furthermore, the results of production and perception experiments suggest that the perception of L2 stops precedes the production of L2 stops. (Chonnam National University)
