Trans pro tip:
You don't have to stress too much about ensuring you always do fem/masc/neutral voice around close friends and family who accept you. To them, you just sound like you.

@JessTheUnstill Strangers, too, TBH. Like, I watched this video on another platform of a girl with really bad voice dysphoria talking about how she desperately needs VFS.

I never would have known she was trans if she hadn't been talking about dysphoria.

Gender detection is a grab-bag of different factors and no one of them is The Thing.

@faithisleaping I do focus the most at the start of conversations - especially on the phone. Cis people tend to quickly lock you into a gender and keep you there regardless. So give them as many signals as you can up front
@JessTheUnstill Yeah, I definitely put in more effort over the phone. On the phone, that and maybe your name are literally the only things they have to go by. In person, though, I have a decent default from a few years of habit building but otherwise don't typically even think about it anymore.
@faithisleaping I still stress about it when I hear recordings - the worst is distorted feedback in video calls - but then again I've never really liked hearing myself. So meh. I just do my usual thing and somehow it works out "well enough".
@JessTheUnstill Oh, for sure. I did a talk earlier this year the conference has presenters approve videos before they go out to make sure stuff like audio sync is okay. I took psychic damage listening to myself.
