Abstract

Purpose : The number of the repatriated Korean students who had overseas study at early ages is increasing. They received foreign education, they can speak international languages, but they have many difficulties in articulation and intonation of the Korean language. This study aims to measure closure and aspiration duration, length of consonants, length of subsequent vowels, and ratio of consonants against subsequent vowels in vowel-consonant-vowel (VCV) syllables. Methods : This study compares the acoustic and phonetic characteristics of repatriated and native students, the ratio of articulation error of Korean plosives, the closure and aspiration duration, and the ratio of the aspiration duration against the closure duration. Results : The ratio of articulation error of Korean plosives between repatriated and native students is 19% and 2%, respectively. The closure duration was significantly longer in repatriated students than in native students. The aspiration duration was significantly longer in repatriated students than in native students. No difference was found in the ratio of aspiration duration against closure duration between the native and repatriated students. Conclusion : This study can be a good reference for estimating the phonetic difficulties of Korean elementary students who had overseas study at early ages.

목 적: 해외귀국학생들의 수가 매년 증가하고 있다. 이들은 우리말의 체계가 완전히 확립되기 전 다른 언어의 영향을 받고 성장하여 우리말의 이해가 어렵고, 발음이 어눌하여 학업이나 교우관계에 문제가 발생하게 된다. 본 연구는 해외귀국학생의 한국어발음 특징을 음향, 음성학적 방법으로 분석하였다. 방 법: 우리말의 파열음(ㅂ, ㅃ, ㅍ, ㄷ, ㄸ, ㅌ, ㄱ, ㄲ, ㅋ) 9개를 VCV 형식으로 녹음하여 폐쇄구간과 기식구간 길이와 비율을 측정하였다. 해외귀국학생 군과 국내거주학생 간 파열음의 조음오류의 비율과 유형을 비교하고 조음위치와 발성유형에 따른 음향음성학적 특성을 분석, 비교하였다. 결 과: 해외귀국학생 군과 국내거주학생 군 간 조음오류 비율은 해외귀국학생 군 19.4%, 국내거주학생 군 2%로 나타났다. 해외귀국학생군의 발음 오류 중 가장 많이 나타난 유형으로 발성 유형의 오류는 경음화, 조음 위치의 오류는 비음화 이었다. 해외귀국초등학생 군이 국내거주 초등학생군 보다 모든 조음위치와 발성유형에서 파열음의 폐쇄구간, 기식구간 길이가 유의하게 길게 나타났다. 그러나 대상군간 폐쇄구간 대 기식구간의 길이의 비율을 비교한 결과 유의하지 않았다. 결 론: 해외귀국학생은 국내거주학생보다 파열음 산출에 조음 오류가 더 자주 일어나며 국내거주학생보다 각 조음위치에 따른 발성유형을 분류하여 정확한 발음을 찾아 산출하는 우리말 발화속도가 느리다는 것을 알 수 있었다. 해외귀국초등학생 발음의 음향음성학적 문제점을 이해하고 추후 해외귀국초등학생의 조음을 평가하는 객관적인 자료에 도움이 될 것이다.
