한국어 화자의 영어 첨가음 발화에 관한 연구

Abstract

The present study investigates Korean speakers' production of the optional phonetic variation such as stop epenthesis between the sonorant and fricative segments in American English. Specifically this study investigates; 1) whether English epenthetic stops are produced by native Korean listeners, given the fact that Korean does not a allow consonant clusters in onsets as well as codas; and 2) whether production of the epenthetic stops could be varied according to the place of articulation of the preceding sonorants. Twelve native Korean speakers and two native American English speakers recorded 120 English non-words with monσsyllabic of CVC1C2 where Cl=/m, n, ŋ, l, and C2=/s, θ, ʃ/ , and measurements of the closure durations and epenthetic bursts were made. The results of the present study show that native Korean speakers produced less epenthetic stops than native American English speakers as expected, showing that first, stop epenthesis is influenced by language-specific syllable structure constraints, and thus English stop epenthesis is not phonetic implementation. However, the production of epenthetic stops was shown to be affected by several factors, including final cluster types and the acoustic cues for epenthetic stops.
