Abstract - This talk reports on an investigation of the effects of perceptual training on the perception and production of Korean second language (L2) learners of English. A central question in L2 acquisition relates to the role perception plays in accurate production and how perceptual training affects this relationship. Research attempting to improve learners' perceptions through high-phonetic-variability training (i.e., training on multiple exemplars uttered by multiple speakers) has demonstrated that perception improvement does not always lead to parallel improvements in production.
In this talk, I report on findings from the effects of perceptual training on Korean learners'' acquisition of two different syllable structures: one that exists in Korean, but allows limited segments (final codas, e.g., push) and one that does not exist (onset clusters, e.g., plight). A pretest/perceptual training/post-test paradigm was used. Results indicate that while perceptual training was successful in improving both perception and production accuracies of participants for final codas, it was less so for onset clusters. Results allow the extension of existing speech perception theories to include the role of syllable-structure constraints as well as provide implications for pronunciation pedagogy.
