The effects of perceptual training on speech production - focusing on Korean vowels

다국어 초록 (Multilingual Abstract)

The purpose of this study is to examine the effects of perceptual training of Korean vowels on speech production. Eight Korean language learners (all native English speakers) were taught Korean monophthongs /i, e, ɛ, a, ʌ, o, u, ɨ/. The subjects were divided into two groups. During three sessions for two weeks, one group received pronunciation education by listening to and following the native speakers' utterances using audio-lingual methods, and the other group received perceptual training by discussing phonetic similarities between language 1 (L1) and language 2 (L2), and paying attention to phonetic differences between the two languages, and repeating the ABX test process. No significant differences were found between the experimental group and the control group in the post-test of perception and production, but the experimental group, which received perceptual training, showed improvement in perception by 19% and production by 9%, while the control group exhibited improvement in perception by 9% and production by 13%. In other words, production capabilities of the group that received perceptual training were slightly enhanced from the result of the pre-test, although it was not accompanied by special speaking practice. This suggests that in pronunciation education, sufficient perceptual training is necessary before pronunciation exercises are conducted.
