Risk of Dysphonia, Presence of Vocal Changes, and Vocal Self-Perception in Brazilian Transgender Women

To evaluate and correlate the risk of dysphonia, the presence of vocal changes and their associated factors, and the vocal self-perception of transgender women.

Observational cross-sectional study in Brazilian transgender women. The analysis addressed their age, length of experience in the gender, perceptual-auditory and acoustic vocal aspects, scores in the General Dysphonia Risk Screening Protocol (DRSP-G), and the Voice Questionnaire for Male-to-Female Transsexuals (TVQ(^MtF)). The sample was divided into two groups based on the grade of vocal deviation (Consensus Auditory-Perceptual Evaluation of Voice)-with (G.W.C.) and without vocal changes (G.N.C.)-to verify the association between the presence of vocal changes and other variables. The correlation between the grade of vocal deviation and DRSP and TVQ(^MtF) scores was also verified.

The sample included 32 transgender women with a mean age of 30.1 and 11.52 years of experience as females. Over half declared themselves Black, and a third of the sample did not have a defined profession. Use of female hormones was reported by 71.9%, the majority without a medical prescription. The mean grade of vocal deviation was 22, the dysphonia risk score was 43.47, and the TVQ(^MtF) score was 59.46. Nasal and pharyngeal resonance was observed in 59.4%, and the mean fundamental frequency (f0) was 156.14 Hz. G.W.C. had a shorter experience living in the redesignated genre. The participants idealized more feminine voices than they currently had. The DRSP-G and TVQ(^MtF) scores had a moderate positive correlation.

The study sample had characteristics compatible with some degree of social and health vulnerability. There was a moderate impact of voice on their quality of life, and despite the high risk of dysphonia, there was a low occurrence of vocal changes. There was a correlation between the DRSP-G and TVQ^(MtF) scores.
