There is a fun quiz, thirteen questions long. You can take it by clicking here: What American Accent do You Have?
Here were my results:
"You have a Midland accent" is just another way of saying "you don't have an accent." You probably are from the Midland (Pennsylvania, southern Ohio, southern Indiana, southern Illinois, and Missouri) but then for all we know you could be from Florida or Charleston or one of those big southern cities like Atlanta or Dallas. You have a good voice for TV and radio.
The quiz said my accent was least similar to that of Americas' Northeast. This matches my experience. When I visited New Jersey, it sometimes took ten seconds before my brain could adjust and filter peoples words as if they were normal English.
Also from the quiz, it confirmed that the midlands accent is very close to the west coast accent.
I was surprised when the quiz said my accent was closer to Boston than to the American "deep South". I find Southerners much easier to understand, and more pleasant to listen to, than Bostonians.
It would be fun to see the results of a quiz that had more than thirteen questions. One important distinction they left out could have been covered by this question: "Does the first syllable of Washington rhyme with the first syllable of warship?"
