This was less interesting than I was hoping for, because it wasn't specific. It said I don't have a non-native English accent. Great, I already knew that. But I'm curious if it could place my regional accent in the United States. I'm originally from the Southern Midwest which has a distinct accent, but have made a great effort to neutralize my accent and believe I now sound neutrally American (what used to be called Nebraska Newscaster).

Sounds like others tried and had similar results (not identifying Australian or Irish accents).
