Yeah, no voice training needed. You get to go through puberty just like the other guys, including an embarassing period of cracking and squawking. That played havoc with my singing - I'd try and hit a note and wind up involuntarily yodelling - but it passed.
The only thing is, if you're a person who has a lot of variation in pitch when you talk, you'll want to train yourself out of that. And some consonants - 's' and 't' - might need re-training unless you don't mind sounding a little gay.
I just speak with the same part of my voice I used to, only now it's an octave or two lower than it was. I always did speak with chest voice though. If you do speak with your head voice (and you might need to look at some singing websites to figure out what you're doing), then you'll need to get used to speaking with chest voice or you'll sound squeaky after it changes.
And if you can't hold a note now, it'll get even harder after your voice changes. Your mileage may vary, but I've found it more difficult singing on pitch than before.
