Listeners rely on the acoustic cues of fundamental frequency and formant frequencies to rate vocal gender or femininity. Typically, as fundamental frequency (fo) and formant frequencies increase, listeners are more likely to identify the speaker as female or rate the speaker as more feminine, but it is difficult to determine the relative contribution of fo and formant frequencies. In this dissertation, I used a mixed-methods approach to examine listener ratings of vocal gender and femininity/masculinity. The quantitative studies aimed to identify differences in the production and auditory-perception of femininity/masculinity in normally phonated and whispered speech. The qualitative study investigated the conscious stereotypes which affect perceptions of female, male, feminine, and masculine voices. To address these questions, normally phonated and whispered speech were used to create two types of naturally produced stimuli where fundamental frequency was present (normally phonated) versus when fundamental frequency was absent (whispered). Acoustically, there were several changes between normally phonated and whispered speech, but these differences were similar across speaker gender identity. In the auditory-perceptual studies described in this dissertation, the results indicated that listeners were most likely to rate speaker gender and femininity/masculinity on the same side of the scale associated with speaker sex-assigned at birth, but ratings of whispered speech were more centralized than ratings of normally phonated speech. Also, listener ratings and the predictors of those ratings varied by whether the scale used terms related to gender, femininity/masculinity, or both concepts. These findings were supported by the qualitative descriptions and themes that listeners used to describe stereotypical female, male, feminine, and masculine voices. Taken together, this dissertation provides evidence for the role of acoustic cues other than fundamental frequency on listener ratings as well as the effect of terminology. This research identifies possible sources of variation within the stimuli, but also across the tasks that listeners are asked to complete. The results have far reaching implications on for the generalizability of the results of previous studies investigating auditory-perception of gender and femininity/masculinity.
