Just wondering. Also what's the normal voice range FTMS usually get? I'm just wondering if you try enough you can talk in like a Baritone and reach Bass tones?
Over time, people's voices typically drop by about an octave from the effects of testosterone, so you'd have to be starting with an unusually low voice to end up with a baritone speaking voice. If you want to extend your low range beyond what T gives you, your best approach would be to work with a good voice coach and find out what's possible. There are DIY methods on YouTube and elsewhere, but some of them carry a real risk of damaging your voice.
My voice was Bass and it's pretty rare. Unfortunately I was stuck with it. I think it came from my mothers side of the family because that grandfather had one of the lowest make voices I have heard. Baritone is much more likely and far more common so there is a good possibility with a proper chest voice, you might reach mid range male. Mostly it will depend on how large your larynx will grow and that's genetics.
As far as voice training, if it hurts at any point, don't do it. The voice is damage if you are to high, to low or to loud. I had proper training and have used a trained voice for many years without damage.
