미얀마인 한국어 고급 화자의 단모음 산출과 지각 연구 = The production and perception of Korean monophthongs by Myanmar’s advanced learners of Korean

다국어 초록 (Multilingual Abstract)

This paper investigates the production of Korean monophthongs by advanced learners of Myanmar in comparison to native Korean speakers, based on findings from production and perception experiments. The results of the production experiment reveal that advanced learners produce the high front vowel /i/ at a higher position than native Korean speakers. Conversely, the low back vowel /a/ exhibits a more varied distribution of F1 values among advanced learners. Notably, no statistically significant differences in F1 and F2 values were observed between /e/ and /ɛ/ in the two groups, with scatterplots indicating overlapping regions for these monophthongs. Nevertheless, advanced learners demonstrate a higher tongue position and more anterior articulation for /e/ and /ɛ/ compared to native Korean speakers. The absence of the Korean monophthong /ɯ/ in the Myanmar vowel system leads to a broader distribution along the F2 axis in production, highlighting a distinct articulatory pattern. Moreover, while there are no statistically significant differences in either F1 or F2 values for the corresponding vowels /u/ and /o/ among advanced learners, differences are primarily observed in F2 values for native Korean speakers. Regarding the results of the perception test, the most notable difference between beginning and advanced learners was found in the misperception rate of the Korean monophthong /ɯ/, which significantly decreased in advanced learners, suggesting an improvement in their perceptual accuracy and discrimination abilities.
