It's not just the voice. You need to chill out. Judging by how you type, you're the kind of kid who says everything in a loud, and possibly bossy way. You get worked up about little things, and don't seem to grasp when something isn't worth mentioning. I don't hate all kids, but I'm annoyed by the ones that either try to boss everyone around or act a little too friendly, joking about every little thing, funny or not funny. "lol i shot u in the balls," or repeating what the in-game characters just said.
Maybe you can try to fix this by starting with only communicating the most important strategies and avoiding anything that sounds too bossy. Try to maintain your inside voice and at least say "please" when asking someone to do whatever you need them to do in the game. Don't get over excited about anything, good or bad.
Also, try to pay attention to how the older guys act. Pick up their sense of humor and stuff, you know? They'll ignore the voice if you still come off as at least a genuinely funny guy.
If you're already a mature acting person trapped in a 14-year-old's body, and there really are just assholes not taking you seriously because of your voice, I don't know what else to say, except that you can at least look forward to getting a deeper voice sometime soon. Puberty does great things.
Of course, that's all a little hard to describe in a verbal environment, but at least I have some more concrete advice for the forums: Use punctuation. It makes everything much easier to read, and is especially useful at The Escapist, where quite a few grammar nazis roam. If you type with capitalization and punctuation, people won't address you here as "Kid," as I see in some comments in this thread.
PS- Sorry for the wall of text. Just trying to give advice, instead of saying "Stop whining, Kid," like some people already are as I type.
