I was searching informations about voice therapy yesterday, and was looking for a therapist near my home, in order to be ready when time will come. I found one who is working now almost exclusively with transgenders, as her name circulated in the community for being transfriendly.
In an interview that woman gave, she explained MTF transgenders have to "unlearn" to use a lower voice, as it was social pressure, that makes boys use it once they've moulted. With her patients, she has to break these habits, coming from strong social codes, she said.
I had no ideas of it, I was convinced it was something natural, the vocal cords lengthen during moulting, lowering the voice into the bass range.
