Production of alveolar flaps in American English by native Korean speakers
Oh Eun-Jin

Abstract
This study examined how native Korean speakers realize the acoustic characteristics of /d, t/ flaps in American English. Fourteen subjects, who had lived in foreign countries for less than one year, read words containing the alveolar stops in flapping environments. /d/ (91%) became flaps more frequently than /t/ (42%). The closure durations for /d/ flaps were significantly longer than /t/ flaps, and the durations of the preceding vowels were not significantly different between /d/ and /t/ flaps. Female learners demonstrated a higher percentage of /t/ flapping than their male counterparts. Differences in flap patterns were observed among individual learners.
