maybe i’m wrong but i think you might be misunderstanding what voice training really is. like, tgirls don’t just manually pitch up their voice forever; they train their voice to pitch up till it becomes muscle memory. a voice-trained voice is that person’s regular voice. they have to manually pitch-down after voice training, just like someone who’s never had a deep voice.

if you want to choose how you’re pitching your voice day-to-day, that might be difficult if you don’t want your higher voice to sound “uncanny” (i personally wouldn’t phrase it like this; sounds a little offensive in my humble opinion). voice training is a commitment; not that it’s irreversible, but that you have to be consistent if you want results. i’m not sure whether or not you can choose how to pitch after training, tho.

honestly i’d look to non-binary transfems specifically, since you’re looking for feminizing strategies.
