Research conducted at ULiège, within the RUCHE research unit, and more specifically within the voice therapy unit, focuses on understanding and supporting the voice in its biological, social, and identity-related dimensions. For over 15 years, special attention has been given to LGBTQIA+ issues through the development of trans-affirmative voice care.
The Voice at the Heart of Identity Issues
The voice plays a key role in gender recognition. After chest surgery, it is the second most common concern expressed by many trans people. Immediately noticeable in social interactions, it can be a source of well-being or, conversely, of suffering when it does not align with one’s identity. In some cases, this issue becomes a priority in care.
The research by Antoine Henrotin and Dominique Morsomme (*) aims to better understand how the voice is perceived and how it can be adjusted in a respectful and personalized manner. The goal is not to “normalize” voices, but to allow everyone to develop a voice that aligns with their goals and life experiences.
Building knowledge with those affected
They are developing innovative approaches, notably “ ” via virtual reality and real-time voice biofeedback , enabling training in situations close to real life. These tools foster confidence and the integration of vocal skills into daily life. Methodologically, they also prioritize community-based research, co-constructing knowledge with those directly affected, as evidenced by the UniCité project.
This work is part of a broader reflection on gender norms and inclusive practices. It helps improve access to care, train professionals, and raise awareness of the realities experienced by LGBTQIA+ people, through collaborations with, notably, Ghent University.
Building Connections
This commitment extends to cultural and societal initiatives. The interdisciplinary group Parole & Écriture, co-founded with writer Geneviève Damas, emerged from the intersection of clinical practice and literary creation, with the aim of breaking down isolation and rebuilding connections. It brings together cis, trans, and gender-diverse individuals in a space for sharing and expression.
A work to raise awareness of trans experiences
An artist from Liège donated a bust- ing a trans woman——to the Parole & Écriture group. Following this donation, the group made a collective decision to entrust it to ULiège’s outdoor contemporary art collection, in order to promote its visibility in the public space and place it in a setting conducive to its exhibition. Unveiled in May 2025 on the International Day Against Homophobia, Transphobia, and Biphobia, this gesture is part of an effort to recognize and combat the violence still experienced by transgender people.
