It was pretty darn accurate. The most similar cities for my dialect according to this were Springfield, MO, Louisville, KY and Lexington, KY.
Weird thing is, although I'm not originally from Lexington, I did live there for a time.
And the general vicinity it places me- Kansas, Missouri, Southern Illinois and Kentucky- is most certainly how I talk.
As Johnny might say
"That is some weird, wild stuff."
