PURPOSE: To determine whether perceptual adaptation improves voice gender discrimination of spectrally shifted vowels, and if so, which acoustic cues contribute to the improvement. METHOD: Voice gender discrimination was measured for ten normal-hearing subjects, during 5 days of adaptation to spectrally shifted vowels, produced by processing the speech of five male and five female talkers with 16-channel, sine-wave vocoders. The subjects were randomly divided into two groups; one subjected to 50 Hz, and the other to 200 Hz, temporal envelope cutoff frequencies. No preview or feedback was provided. RESULTS: There was significant adaptation in voice gender discrimination with the 200 Hz cutoff frequency, but significant improvement was observed only for three female talkers with F(0) > 180 Hz and three male talkers with F(0) < 170 Hz. There was no significant adaptation with the 50 Hz cutoff frequency. CONCLUSIONS: Temporal envelope cues are important for voice gender discrimination under spectral shift conditions with perceptual adaptation, but spectral shift may limit the exclusive use of spectral information and/or the use of formant structure on voice gender discrimination. The results have implications for cochlear implant users and for understanding voice gender discrimination. |
