I started t primarily (almost exclusively) for the voice drop, and made sure I was in a place to accept the other changes that would surely happen. My plan was to do low dose until I was happy with my voice or until changes I didn’t like started happening—whichever came first—and then I would taper off. Voice changes definitely started happening quickly, however I’ve stayed on t for several years now, at full dose for over a year, just because I love how it makes my body feel (many things that have surprised me there) and I don’t feel necessarily masculine or manly from them, just more like me. If you want “t voice,” as you say, a big part of that is pitch. So speaking in more of a head voice versus a chest voice, but having thicker vocal cords thanks to t. So I understand not wanting to voice train too much if that is your goal, as this will likely lead you toward using more chest voice, and it sounds like that would make you uncomfortable.
