This study examines the production of English word-final codas by Korean speakers. First, we investigate how Korean learners phonetically realize English word final codas. The second question explores what factors exert an influence on production type. Results show that Korean speakers' production most favors the released type and then prefers the release and vowel epenthesis type and the unreleased type. This finding indicates that Korean learners are making progress toward targetlike production while retaining the transfer from Korean syllable structures. Finally, their production type significantly differs by the number of codas, grammatical condition, preceding vowel, and following linguistic environment.
