한국인의 영어 문장 발음에 대한 한국인/원어민/ILT(Interactive Language Tutor) 평가 점수 사이의 상관관계

Correlations between pronunciation test scores given by Korean/Nativel/ILT(Interactive Language Tutor) raters against the Korean-spoken English sentences

This study carried out an experimental English pronunciation assessment to see the differences in the relationship between the different rater categories. The result shows that i) correlation between Korean and Native American raters is high(r=.98) enough to be considered reliable, ii) previous instructions about assessment rubric and the knowledge about English phonetics and phonology exert little influence on the rating scores, iii) correlation between the automatic ILT(Interactive Language Tutor) rating using speech recognition technology and Natives' rating is stronger than that between ILT and Koreans' rating.
