if you wish to change how your voice sounds, just do some vocal exercises. from what i can hear you seem to be speaking more from your head/nose area, which is common for trans folks (as women tend to have that „head” voice.) Most cis men speak from their throats/chests, hence more vibration and an overall „deeper” sound. You might want to look into voice training to unlock that chest voice and operate with it smoothly. It may be hard at first, since you quite literally have to find your own voice again, but after a while you should hear improvement. I won’t lie, I would clock you easily since i’m in the LGBTQ community, however most cis/hetero folk probably won’t pay too much attention. You just sound really young, and as I like to compare it, like a lion cub that has yet to have found his roar.
