베트남인의 한국어 폐쇄음 산출에 대한 한국인의 지각 연구

Abstract

The purpose of this paper is to investigate the perception patterns of Koreans regarding the production of Korean stop consonants by Vietnamese Korean language learners. For this purpose, an experiment was conducted on Koreans' perception of Vietnamese learners’ production of Korean stop consonants.
 The results of the experiment show that when the presentation sound is located at the beginning of the word, the correct answer rate was ‘/ㅌ/ 89%) > /ㅋ/(88%) > /ㅍ/=/ㅂ/(84%) > /ㄱ/=/ㄸ/(74%) ) > /ㄷ/(72%) > /ㅃ/(65%) > /ㄲ/(61%)', and in the case of word-medial onset consonants, ’/ㅍ/, /ㅋ/(91%) > /ㅌ /(88%) > /ㄷ/(68%) > /ㅂ/(61%) > /ㄸ/(60%) > /ㄲ/(51%) > /ㅃ/(46%) > /ㄱ/(40%)’. Except for the case of /ㄸ/ in word-initial and /ㄱ/ in word-medial, accuracy was found to be high in the order of aspirated consonants > plain consonants > tense consonants for both word-initial and word-medial positions. The percentage of correct responses in the word-initial environment was higher than that in the word-medial environment, and this was revealed more clearly through matrix analysis. In both word-initial and word-medial environments, when the target sound was ‘plain’, it was confused with ‘tense’, when it was ‘tense’ it was confused with ‘aspirated’, and when it was ‘aspirated’ it was confused with ‘plain’. Looking at the correct rate for each following vowel, except for the word-medial plain consonant (/ㅣ/ > /ㅜ/ > /ㅏ/), in all other cases, the correct rate was high in the order of /ㅣ/ > /ㅏ/ > /ㅜ/. This result shows that the correct response rate for the following vowels decreases as the vowels move from the front vowels to the back vowels.
