Korean students of Japanese often have difficulty with perception and pronunciation of voiced and voiceless plosives in Japanese. For this study, perception and pronunciation experiments were carried out on 15 beginner-level Korean students of Japanese. This research used a perception experiment which consisted of consonant + vowel + consonant + vowel (CVCV) combinations of voiced and voiceless plosives of Japanese. The three types of Korean plosives (aspirated, forced, lax) and the two types of Japanese plosives (voiced, voiceless), were analyzed using VOT (Voice Onset Time) at the time of pronunciation. With perception, many Korean students frequently misunderstood the word-initial voiceless plosives of Japanese, mistaking them for voiced plosives. With pronunciation, there was a possibility that the voiced plosive of Japanese was perceived as similar to the lax plosive of Korean, both in word-initial and in word-final positions. Furthermore, Korean students of Japanese experienced interference from their mother tongue while studying Japanese plosives; both perception of word-initial voiceless plosives and pronunciation of word-initial voiced plosives were affected.
