초록

이 논문은 리듬 및 유창성 지수와 한국 대학생이 읽은 영어 발화의 리듬 및 유창성 청취 평가가 어떤 관련성을 가지는지 분석한 연구이다. 이를 위해 대학생 17명이 'The North Wind and the Sun' 문단을 읽고 영어 발음 수업 사전, 사후 두 차례에 걸쳐 녹음한 것을, 대학원에 재학 중인 현직 영어 교사 및 예비 영어 교사 7명이 리듬 및 유창성에 대한 청취 평가를 진행하였다. 또, 선행 연구에서 언급된 리듬 및 유창성 지수 중 14개 지수를 사용해 각 발화 자료의 지수를 추출하여 지수와 청취 평가의 관련성을 분석하였다. 지수를 분석한 결과 %V, VarcoV, nPVIV에서는 선행 연구의 영어 원어민 지수와 거의 비슷한 양상을 보였고, ΔV, ΔC, VarcoC에서는 원어민보다 높았으며, 발화 속도는 원어민보다 느렸다. 한국 대학생들이 일부 리듬 지수에서는 영어 원어민과 비슷한 양상을 보인다고 할 수 있다. 리듬 및 유창성 지수를 사용하여 리듬 평가 점수와 유창성 평가 점수를 예측할 수 있는 최적의 모델을 탐색한 결과, 리듬 및 유창성 평가 모두에서 유창성 지수인 휴지 비율, 조음 속도, 발화 속도 등이 리듬 지수들보다 평가 점수를 예측하는데 더 큰 기여를 하는 것으로 나타났다.

This study investigates the relationships between rhythm and fluency indices and listeners' ratings of the rhythm and fluency of Korean college students' English paragraph reading. 17 university students read and recorded a passage from "The North Wind and the Sun" twice before and after three months of English pronunciation instruction. Seven in-service and pre-service English teachers in graduate school assessed the rhythm and fluency of the utterances. In addition, the values of 14 indices of rhythm and fluency were extracted from each speech and the relationships between the indices and the listeners' ratings were analyzed. The rhythm indices of the speakers in this study did not differ significantly from those of native English speakers presented in previous studies in %V, VarcoV, and nPVIV, but were higher in ΔV, ΔC, and VarcoC and lower in speech rate. The level of rhythm and fluency demonstrated by Korean college students was comparable, at least in terms of objective values for certain indices. The fluency indices, such as percentage of pauses, articulation rate, and speech rate, significantly contributed more to predicting both rhythm and fluency ratings than the rhythm indices.
