I wasn't aware that Midwesterners like me have any particular accent. If so, it doesn't apply to me. I've talked to Lekana on the phone before, and our 'accents' are indistinguishable, IMO...and I live in Indiana and she's in Wyoming.
As for my 'accent', I usually speak very clear, proper English. It changes when I'm amused or excited though, and I sound very casual and (ehhhh...) somewhat girly. (Yes, I am often mistaken for a girl by my voice alone. )

Don't get me started on how I sound when I'm caffeinated though. I tend to speak in the before-mentioned excited voice, but about 3 times faster, and without even realizing it until someone tells me to slow down.
