About the Research – Creation Project

A lower voice is one of the of the changes most desired by many transgender people assigned female at birth (AFAB) who take testosterone. While taking testosterone does lead to a lower voice, some people experience vocal problems, like a persistently weak, hoarse, or unstable voice, after starting T. The lack of systematic information on transgender voice transitions makes the decision to start testosterone especially difficult for transgender singers, because they can either take testosterone to transition, but risk losing functional use of their voice, or continue living with a body that does not align with their gender.

We address this issue by (1) conducting a case study on the voice transition of an assigned-female transgender singer taking testosterone, Ari Agha, and (2) create an interdisciplinary social justice performance to explore connections between voice and gender.

Case Study of Ari’s Voice Change (Research)
To serve as a baseline, we began collecting information about Ari’s voice before they started taking testosterone. We used many sources to document Ari’s voice change, including video of vocal folds (stroboscopy) and acoustical analysis of their voice, video recording of Ari’s voice lessons with Laura Hynes (voice faculty at the University of Calgary, she/her pronouns), and written records of Laura’s observations about changes in Ari’s voice. Ari chronicled their personal experience of going through a voice change in video and written blogs. In addition, we tracked hormone levels to assess whether these are connected to changes in Ari’s voice. 


We’re excited to announce the publication of a journal article documenting Ari’s singing voice change with testosterone:

Ari Agha and Laura Hynes (March/April 2022) “Exogenous Testosterone and the Transgender Singing Voice: A 30-month Case Study,” Journal of Singing, 78 (4), pp. 441–455, https://doi.org/10.53830/YKWM3774.

Social Justice Performance (Performance Creation)
In September of 2019, we premiered an interdisciplinary social justice concert featuring Ari and  Laura Hynes (voice faculty at the University of Calgary, she/her), a quartet of singers:  Cassandra Bessette, Tim Carter, David Latos, and Lizz Windnagel, and a choir.  The creative team was Ari Agha, Laura Hynes, Bruce Barton, and Lizz Windnagel. The performance included solo singing, choral music, documentary film, and storytelling to share how Ari’s voice changed, celebrate a supportive transition experience, and explore connections between voice and identity.

An updated version of  the social justice performance was  premiered in the summer of 2022.  Check out the Events/Performances Page for details!
