초록
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.
Abstract
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.
