The aim of this study is to reveal whether Chinese learners of Korean language have different auditory criteria on two Korean vowels /ʌ/ and /o/ from Korean native speakers. A perception experiment was conducted on a continuum consisting of eleven synthesized stimuli. ROC analysis was performed to calculate the boundary criterion of two vowels. The perceptual judgment of 19 Mandarin native speakers and 20 Korean native speakers showed that the two groups have same boundaries for the two vowels on the continuum. The boundary criterion between /ʌ/ and /o/ was estimated to be located between the stimulus no. 4 (F1 = 461Hz, F2 = 803Hz) and no. 5 (F1 = 448Hz, F2 = 780Hz). Since no difference was found between the native and learner groups in terms of Youden index associated criteria in their ROC curves, this result suggests that pronunciation training should get more concerning in the field of language education to improve the pronunciation accuracy of Chinese learners.
