I love to play with accents and characters!
Americans are easy from coast to coast :)
I do the Jersey shore, the new yorker, the Boston, the Midlander, the west coast rapper. If I don't do a specific voice, I can learn it.
I can do many variations of the gay lisp (why is it so fun? lol).
Characters whom English is not their first language are a favorite. Such as the Mexican American, Oriental, Ruski, Canadian, European, Arabic, French. I love to get silly with these.
I can make myself sound quite old or young. With a little effort I feel like I can learn or copy other people as well.
As a narrative voice I can be smooth and clear. On the other side of that coin I can be quite coarse, raspy, harsh and a hardened smoker voice.
