"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.

I was born in the North Shore area of Massachusetts. Moved to Wyoming at 25, now I'm in western Colorado. Never have more than passed through the Midland.

I do add an "r" occasionally on to the end of a word that doesn't need one.

Few people would guess that I'm from New England, but I can sure spot a NE accent when they show up around here.
