Abstract

|
This study examined which acoustic cue(s) that Korean learners of English give weight to in perceiving English lexical stress. We manipulated segmental and suprasegmental cues in 5 steps in the first and second syllables of an English stress minimal pair “object”. A total of 27 subjects (14 native speakers of English and 13 Korean L2 learners) participated in the English stress judgment task. The results revealed that native Korean listeners used the F0 and intensity cues in identifying English stress and weighted vowel quality most strongly, as native English listeners did. These results indicate that Korean learners’ experience with these cues in L1 prosody can help them attend to these cues in their L2 perception. However, L2 learners’ perceptual attention is not entirely predicted by their linguistic experience with specific acoustic cues in their native language.
