TruVox Web-Based Software for Vocal Pitch Training in Transgender Women: Development and Single-Session Evaluations

While the pitch training module should not be considered a complete GAVT package, TruVox represents a promising foundation for further GAVT software because it was perceived as usable and motivating and allowed participants to improve their exercise performance. To our knowledge, TruVox is the first GAVT software that combines real-time voice visualization with structured exercises, and this study represents the first quantitative human subjects evaluation of GAVT software. In the future, TruVox will be expanded with additional modules such as resonance training, then tested in longer-term trials.
