Hello all

I was just wondering if any of you do your own voice acting for your animations. If so, is it normal to get pains and aches. I'm making most of the voices for my characters and some of the voices i do, hurt me cause i have to make my voice high or low or make it sound weird and then it starts hurting.

Also, i feel like i'm going through my scrip and recording the characters lines. But then i forget how to do the voice of a certain character. I can go back and listen to a piece i recorded earlier but it's still kind of difficult to make it the same. 

ANy tips?
