There is also some controversy regarding the use of a bigender voice. A person may want to have both a masculine and a feminine voice in their vocal repertoire, possibly to fit with their own bigender identity, or to read as a different gender in different contexts. Many clinicians will not train bigender voice, arguing that it decreases the opportunity for practice, and it may be difficult or even damaging to the vocal folds for the person to switch from one voice to another. However, Davies, Papp and Antoni (2015) reference the ability of actors to use different accents and dialects, and people to learn different languages as a sign that training a bigender voice may be a viable treatment goal.
