The Role of Self- and Listener Perceptions of Femininity in Voice Therapy

Voice therapy, especially during male-to-female transition, typically targets acoustic measures of voice. Self-perception of femininity may be a valuable measure to incorporate into clinical protocols and empirical investigations of treatment efficacy. Speech samples of 20 male-to-female transgender and 10 cisgender speakers were rated by speakers and 25 listeners. Mean fundamental frequency (Fo) and semitone range, but not perturbations, of the speaker's voice were strongly related to speaker- and listener-rated femininity. Listener-rated femininity strongly correlated with speaker's self-rated femininity. Results of this study provide guidance and methodology for incorporating the speaker's self-perceptions of overall and vocal femininity into voice therapy.
