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 @faithisleaping my "solution" as someone who doesn't pass in any way yet and is currently too intimidated by the effort to try: I just say explicitly that I'm trans.
