A Study on Realizations of English Stress and Vowel Formant Frequency by Korean Learners
Kim Ji-Eun

Abstract
This study investigates twenty four Korean females' production of English front vowels focusing on the distinction in /i/ vs/?/ and /?/ vs /©¡/ and formant values of stressed and unstressed vowels compared with those of native English speakers. TheKorean learners were asked to read a textbook passage which includes ten sentences including target vowels. The majorresults indicate that: (1) Korean learners have trouble producing a distinct version (tense and lax) of front vowels in theparagraph reading; (2) The vowel space of the stressed vowels in a paragraph is smaller than that of embedded sentences;and (3) The vowel quality of the unstressed vowels produced by the Korean learners is similar to that of the native Englishspeakers. The findings from this study can be applied to the pronunciation teaching for the Korean learners of English vowelsand realization of English stress.
