For those of you on Pharma HRT, has it change the quality, pitch or control of your voice?

I read somewhere that for some, it does.

No, nothing noticable directly, But it has altered my inclination to do so, and so now I`v noticed (as have others) that my voice is becoming a little more femme without effort.
I will point out that I used to talk on CB radio for Hours as a female before, so it`s not That hard to gradually get back there again on daily basis now.
but no, there`s no Physical thing that I can feel happening and can still do my male voice if I wanted to (and I don`t).
