I think the accents in eastern Kentucky and West Virginia would be closer than general Southern. They're similar to the Southern accent but without the drawl, and tend to be very rapid and clipped with vowel sounds that I still have to interpret for people. My "i" sound, for example, is closer to what you say when a doctor puts a tongue depressor down your throat. People have frequently heard me and said, "That's a vowel?!!!"
You mean like the girl in the video below.
