Gender-affirming Voice Training With Visual Feedback

No results posted yet for this study

Summary

The goal of this clinical trial is to learn if prototype software can be used to train vocal pitch and resonance in trans women. The main questions it aims to answer are:

* How regularly would trans women use the prototype voice training software as "homework" between human-led voice training sessions?
* In such a setting, how usable and motivating would the training software be?

Participants will first have their voice measured, then take part in four virtual sessions (one per week) led by a speech-language pathologist. In each session, the clinician will guide the participant through several voice exercises both with and without the software. Participants will be asked to use the software to exercise on their own for about 2x 15 minutes a day between virtual sessions.

Conditions

  • Transgender Women
  • Voice Alteration

Interventions

BEHAVIORAL

Visual-acoustic biofeedback: experimental

Visual-acoustic biofeedback treatment incorporates elements of traditional voice training, including auditory models, verbal descriptions of articulator placement, and cues for repetitive motor practice using images and diagrams of the vocal tract as visual aids. Our experimental software will provide several options for visualizing the fundamental frequency of the voice (for targets involving vocal pitch) and for visualizing vocal tract resonances. Custom targets for pitch and resonance will be created for each participant based on their baseline voice characteristics and personal voice goals. They will be encouraged to attend to the visual display while adjusting the placement of their articulators and observing how those adjustments influence the proximity of their output to the target.
