I have a little Yankee in me. Orange = arange. I can easily pull off the "aw" in coffee, dog, call, etc because I'm from New Jersey
I don't think I have a true accent. At least, my friends from different states have never said anything. I have a slight lisp + a tongue thrust so my words are just jumbled, but I don't have true specific accent. I think the only thing that separates me from people in NY is my slang
