My voice already makes me sound Canadian, (I was raised in America) mixed with me speaking Cantonese to family, and learning voice acting from the acting teachers I've worked with.
A bunch of autistics I know share voice manipulation. My voice can easily be strained as a bass-baritone, but I have made the style mold to my own when I want to try.
