Both advanced- and beginning-labeled native English learners of Korean and Korean native speakers took part in the production experiment which examined acquiring some selected Korean suprasegmental factors such as F0, speech rate, and boundary cues. In the test, both English groups showed comparatively low mean value of F0, and higher value of F0 in the initial part of the sentences. Beginning-labeled English learners of Korean exhibited a slower declination tilt and slow speech rate, while advanced-labeled English learners of Korean hold a steeper declination tilt and comparatively fast speech rate. The results suggest that (1) L2 developmental patterns of production clearly have been influenced by L1 system, and (2) Each phonetic cue has different developmental stag
