The Experimental Study on Korean Monophthong of Taiwanese Learners of Korean-Focusing on College Students Majoring in Korean

대만 한국어 학습자의 한국어 단모음에 대한 실험음성학적 연구 -한국어를 전공하는 대학생을 중심으로-

The purpose of this study is to acoustically analyze eight Korean monophthongs produced by 29 Taiwanese learners of Korean and 20 native speakers of Korean, and to compare their pronunciations in experimental phonetics. Using the first formants(F1) and the second formants(F2) of Korean monophthongs, we can estimate the tongue positions of vowels produced by participants. In order to compare them directly, we had to normalize participants' F1 and F2. The result shows that almost all vowels of the Taiwanese learners are significantly different from those of Korean native speakers in their F1 and F2 values without the /ㅏ/ vowel. In particular, when pronouncing Korean monophthongs, the Korean learners of Taiwan had a narrow area of the place of articulation compared to the Korean native speakers except for back vowels. Finally, it shows that the Korean learners in Taiwan had a narrower range of articulation and articulated the vowels towards the back a little comparing to the Korean native speakers.
