In this paper, I show that pitch patterns influence native speakers of Korean in their perception of voiced and voiceless sounds in Japanese. It is shown that speakers of Korean, a language which does not have the contrast between voiced and voiceless sounds, rely on the difference of the pitch patterns rather than the voicing sounds. More specifically: 1. It was confirmed that, roughly speaking, higher pitch occurs in association with voiceless sounds, while lower pitch occurs in association with voiced sounds. 2. It was confirmed that Korean speakers have little problem perceiving voiceless sounds when they are accompanied by a clear high pitch, and voiced sounds when they are accompanied by a clear low pitch. In other cases, the rate of perception errors was high. 3. In a follow-up experiment, the pitch pattern of voiced sounds was substituted with that of their voiceless counterparts and that of voiceless sounds with that of their voiced counterparts. The results showed that Korean speakers are apt to perceive voiceless sounds as voiced when the accompanying pitch is low, while they tend to perceive voiced sounds as voiceless when the accompanying pitch is high. Japanese speakers showed the same tendency, but with a lower rate of errors in perception.
