Oh, Midwesterners definitely have a definable accent. I can tell a Midwesterner apart from anybody in a crowd of people. Also, I can pretty easily recognize the different versions of the "southern" accent. The most prominent accents in the South are South Carolinian, Virginian and Texan. Then to a lesser extent are North Carolina and Georgia. I have a bit of a North Carolinian accent, which is actually kind of plain. Also, Louisiana accents are easily recognizable. The only ones I have problems with are Tennesseian, Kentuckian and Alabama accents, because they don't sound like anything special to me.
