The aim of this paper is to investigate the occurrence of vowel devoicing in both Korean and Japanese spoken by Korean learners of Japanese. Close vowels between voiceless consonants in Korean and Japanese were analyzed acoustically. The remarkable character of Korean vowel devoicing is that the occurrence rate of devoicing differs considerably among individual subjects, irrespective of dialect. As for Japanese spoken by Korean learners, there is a high correlation between occurrence rates of devoicing in Korean and in Japanese.
