영어 및 일본어 원어민 한국어 학습자의 초분절 요소에 의한 유창성 평가 비교 연구

A study on the fluency judgment of the suprasegmentals for the native English and Japanese learners of Korean

Both of advanced- and beginning- native English and Japanese learners of Korean took part in the L2 acquisition experiment. After thirty-eight L2 subjects’ speech was assessed based on twenty Korean listeners’ judgment, suprasegmental measurement for Korean speaking was analyzed. The results show that (1) L2 developmental patterns of suprasegmentals clearly have been influenced by L1 system, and (2) Each suprasegmental cue has different cue weight in fluency decision. Generally Japanese learners of Korean easily acquire Korean prosody, but the difference of fluency between the two advanced groups decreased. Also statistical regression analysis show that speech rate is the most powerful explanation cue in the fluency judgment, but the F0 range shows the least.
