[Contributions of temporal and spectral cues to Chinese tone recognition in the continuous interleaved sampling strategy].
Recent studies have revealed temporal waveform envelope cues as a function of time having significant influence on tone recognition in continuous interleaved sampling (CIS) of cochlear implants. In this study, temporal cues of speech signal have been modulated so that to different tones have nearly the same temporal waveform envelope. The processing signal is named modulated signal. The modulated signals and original signals are processed through software emulations of cochlear-implant signal processors. The recognition score of the modulated signals and originals are compared. The result indicates that temporal cues have great influence on tone recognition, but spectral cues are the principal factor determining the identification of tones.
