Abstract

|
The purpose of this experimental study was to investigate characteristics of English vowels uttered by Korean regional dialect speakers. Ten English mono-syllabic words, and eight Korean mono-syllabic words, wee uttered six times by nine female graduate students from three areas; Seoul, Yongnam and Honam. Formant frequencies were measured from sound spectrograms made by the PC Quirer. Results showed that Seoul dialect speakers uttered English vowels more similar to those uttered by English native speakers than did the other dialect speakers. In particular, Yongnam dialect speakers have articulatory problems pronouncing the back vowels(/u/, /υ/, /??/), while Honam dialect speakers have problems pronouncing the front vowels(/i/, /Ⅰ/, /ε/, /æ/). Even though each group has different problems pronouncing English vowels, Korean speakers generally have difficulty in discriminating tense vowels(/i/ and /u/) from the lax vowels(/Ⅰ/ and /υ/). It appears that the width of Korean speakers´ articulatory movements is comparatively narrower than those of native English speakers.
