Abstract

Most foreigners who learn Korean cannot correctly perceive and articulate a three-way distinction of Korean stop consonants(lenis, fortis, aspirated). One explanation of this phenomenon argues that they focus on more than one specific dimension of phonetic contrasts in their own languages and may thus attend the same dimensions when they listen to Korean. Such processing strategy should be inappropriate in perceiving Korean. We examined a hypothesis that decreasing the information associated with the dimension that are focused on in foreigners' mother tongues and thus inappropriate for the perception of the phonetic contrasts in Korean can make learners attend other dimensions that are appropriate for Korean speech perception. To test this hypothesis, we manipulated the amplitudes of Korean speech sounds. Experiment 1 examined the effect of manipulating the amplitudes of speech sounds on perception of a three-way distinction of Korean stop consonants with Korean and Japanese participants. Experiment 2 examined whether the amplitudes manipulation affects Japanese participants' learning a three-way distinction of Korean stop consonants. The results of two experiments suggest that decreasing amplitudes of speech sounds can make learners attend to the dimensions that are appropriate for the three-way distinction of Korean stop consonants and that such attention facilitates Japanese learners' perceptual learning of the three-way distinction.
