Adapted melodic intonation therapy can help raise trans women’s singing and speaking fundamental frequencies

Abstract

Aim

Voice interventions for transgender individuals can address several speech and voice parameters – fundamental frequency, resonance, intonation, rhythm, and intensity. In this study, we focus on fundamental voice frequency and build on existing research to test one technique that has been shown in a preliminary study to effectively adjust fundamental voice frequency in line with clients’ goals.

Method

More specifically, we employed an adaptation of melodic intonation therapy (MIT) to assess whether it can raise trans women’s average fundamental frequency to a significant degree. Eleven trans women participated in two one-to-one therapy sessions, four weeks apart.

Results

Results pointed to a statistically significant rise in both their singing and speaking fundamental frequencies following the adapted MIT therapy sessions. Participants were also successful in imitating upward fundamental frequency contours when singing and in producing them independently in the speech modality.

Future Directions

Longitudinal studies are warranted to determine whether the observed positive results translate into long-term benefits.
