This is gonna sound weird, but when I create and work on a voice, I “method act” the voice I’m working on. So if the voice I’ve created is high pitched, weasel-ly, I find myself hunching my shoulders, crouching a little bit, and trying to inhabit the body of a smaller person. I can’t just do the voice.
I’ve watched several voice actors over the years who just walk up to the mic and BOOM character comes out without issue. Wondering if it’s a time and practice thing (I practice voices all the time, everywhere, seriously) or if there’s anyone else out there like me.
