omg.. PS3?
Where's the bann button?!
just joking
also, here's some tips on voice acting if you're actually willing to go for it:
Get a good microphone which can record your voice really nice with as less background noise as possible (I have a Samson C01U myself, and many other voice actors use it as well)
try to 'study' some accent that you can do to perfect them, the more awesome you sound, the better you will be.
and my last tip would be: always ask the director for more information about your character if you're not sure what your lines are about.
it's always better to know something about the character you're playing than just to get the lines and not knowing where he is from, what accent he needs, what type of voice he has and mostly you don't even know in what situation the character is when you have to say the lines, always more handy if you know you're in a fight and you're supposed to be screaming instead of just talking to another 'player'.
