Summary: Chris
This study investigated the perceptual representation of voice gender. Two approaches were adopted in the study. First, the study aimed to see whether perception of voice gender is categorical by using identification and discrimination tasks. Second, the study investigated if voice gender is more of an auditory-based level or a higher abstract level of processing by using selective adaptation techniques. Experiment 1 showed that the perception of synthesized stimuli was not categorical. Experiment 2 was designed to test if there was a third category between the synthetic voice continuums. Results showed that the data for the male and female responses were similar to Experiment 1, indicating that voice gender was usually not categorized as more than two genders. Experiment 3 aimed to test if overall auditory overlap has an effect on the adaption of voice gender by conducting selective adaptation experiments. Results showed that low level auditory perception was supported. Experiment 4 was designed to test if the decomposed parameters of overall overlap (F0 and formant) affect the adaption of voice gender. Results showed that no adaptation was found, suggesting that the individual voice parameters were not important by themselves, but important as a whole. Experiment 5 explored if ambiguous adaptors and biased instructions would favor the biased gender. Adaption was not found for male subjects but was found for female subjects. It was concluded that males used continuous perception and females used categorical perception.
