Abstract

A study was conducted in which listeners evaluated 456 audiotaped voice samples produced by 19 boys and 19 girls. Thirty listeners (undergraduate and graduate students studying speech-language pathology and audiology at Western Michigan University) identified the gender of these voices. It was expected that greater than chance accuracy of responses would result due to acoustic cues (fundamental frequency, formant frequency, and intonation) present in the voice. The data from this study support this hypothesis. Identifications for girls were correct 56% of the time, while identifications for boys were correct 71.5% of the time.
