Because they are professional too

How many times do the performances of these men and women go unheard of? How many times do they get shoved aside and look down upon because they are ''just doing a silly voice in front of camera. Whether you are aware of it or not they are the voices of many, and I mean MANY characters you've grown to love in video games, cartoons, anime or even movies. So please, acknowledge their work? It can't be replaced by Hollywood actors.

Well...

Don't go there dude. Your voice was replicated by a number of guys so don't pretend EVERYONE can do voice acting.
