This study examines the changes in acoustic manifestation accompanying the English low pitch accent(L*) produced by native speakers and Korean learners of English. To obtain more reliable results, the changes of the acoustic feature values (F0, intensity, syllable duration) were normalized by a mean value of each utterance and the whole duration of each L* word. Acoustic values of focused words in different locations (initial, middle and final position in a sentence) were compared between the two groups. Statistical analysis showed that English native speakers produced L* with lower F0 than Koreans learners in all focus locations and lower intensity only in one location (initial position in a sentence). It also showed that a longer duration of L* syllable at the end of a sentence was found in utterances produced by native speakers than in those produced by Koreans learners
