No surprise here, although they are wrong about if being from New York City that one can tell...people can't with me. I did say the other day I'd call my accent Northeast Generic rather than New York... :D
What American accent do you have?
Your Result: The Northeast
Judging by how you talk you are probably from north Jersey, New York City, Connecticut or Rhode Island. Chances are, if you are from New York City (and not those other places) people would probably be able to tell if they actually heard you speak.
Philadelphia
The Inland North
The Midland
The South
Boston
The West
North Central
What American accent do you have? Also came out strongly in Inland North...what is that, like Michigan? Chicago?
