How to change your voice on headset for xbox360?

I have an xbox 360 headset and when I play online other gamers say my voice sounds like a kids voice, even though im in my 20s. I hear other gamers who have a mans voice , now my question is how to I change my headset voice to a man%26#039;s voice?|||have no clue sry dude|||http://answers.yahoo.com/question/index?鈥?/a>|||Try talking in a deeper voice|||Try talking deeper, i think that XBox removed %26quot;Voice Masking%26quot; from the 360 its just as annoying to listen to a voice masker as it is a little kid, it may also be the mic, but i doubt it. your best bet is just talking deeper, or not talking at all =/
