I don't have anything on file to compare it to but if I did I'd put up a bit of me saying stuff before and now. My speaking voice dropped significantly without reason, I'm not sick and haven't been doing the boom your voice exercises (tried a long time ago in order to sing Green Day songs with my squeaky fifth grade voice) or anything, also pre-T for painfully obvious reasons. But I opened my mouth and had to shut it again to stop the stream of curses that was about to come out of it. Seriously in disbelief over it, sounds like a younger version of my dad's voice.
And I was able to look at myself in the mirror and say, "Damn, once we get these things off that's going to be one nice-looking chest". Yay sorta-narcissism :P
Now...if you'll excuse me, I'm going to go enjoy my manly voice before Murphy steps in and takes it back. This is beautiful.
