It has been known that cochlear implant (CI) listeners have difficulty in vocal emotion perception. Researches on vocal emotion perception of CI listeners have been studying ways to simulate responses of CI listeners by using noise-vocoded speech (NVS) as CI simulations with normal-hearing listeners. The purpose of this study is to clarify the relative contributions of spectral and temporal cues in vocal emotion recognition for NVS. In the simulation, the spectral cue can be numbers of speech processing channels are 4, 8, and 16. The cutoff frequency of the envelope filters ranged from 0 to 64 Hz. Sentences were produced by one female talker according to five target emotions: neutral, joy, cold anger, sadness, and hot anger. As a result, the recognition rates significantly improved as the cutoff frequency was increased for all emotions. Moreover, the number of channels only effect the recognition rate of neutral, joy, and cold anger. The results suggest that temporal cues contribute to vocal emotion recog...
