This study examines the high-low pitch range differences between Korean and native English speakers´ utterances of 36 English sentences, and explores the role of the pitch fluctuation range in the pronunciation assessment. Findings are: i) Korean speakers implement half as much pitch fluctuation as the native speakers with the achievement rate of, on an average, 47%. Especially, pitch fluctuation range is below the average in the sentence types of exclamation, yes-no & wh-questions, ii) the reason why Korean speakers´ pitch fluctuation range is only half the range of the native speakers is that Korean speakers do not raise the pitch at certain sentence positions so much as the native speakers, and iii) the range of pitch fluctuation plays an important role in distinguishing the utterances of the native speakers from those of Korean speakers, but does not in rating the English utterances among Korean speakers.
