I completely understand where you're coming from. D: I think it's easy to get self-conscious about changing your voice in front of people because unlike the changes made to your body by HRT, it's something that is completely on you to change, and it can be easy to fall into the trap of feeling like you're being "fake" or "unnatural" by consciously modifying your voice around others. I wouldn't mind around someone who didn't know me from before, because then they'd have no point of reference for what my voice used to be like, but I feel like if I change my voice around people who knew me in my previous life, everyone is going to be consciously aware that I'm changing it, and it's going to be the elephant in the room that everyone is paying attention to but nobody wants to point out. For that reason, my voice is still basically just the same as it's always been, and I've struggled to change it at all. I'm lucky to have quite a high pitched, gentle voice for someone who went through male puberty, and I don't think it's "male" enough to out me most of the time, but it's still one of these things that I would really like to work up the courage to change, and which I really wish would change on its own.
