How do you sound?
"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.
Midland here too.
Well, with all the moving around you are doing, it will be hard to keep any regional accent.
What? You do not compute?
BTW: For our Aussie and English friends, there are quizzes at the site for their accents as well.
