I don't know that I sound like anyone particularly famous.

Having been born and raised in Louisville, KY, living almost all of my adult life here (except for the year I was working in Cleveland), and having received a university education, I am told by folks from other parts of the country that I have almost no discernible accent.

Using the test OCRichard provided in his thread, I have a neutral American accent (as found in the Midwest region and used by most US newscasters).

I can, however, slip into a Kentucky/country accent, particularly when I get extremely tired and don't concentrate on my elocution. There is a tape recording of me when I was five years old (I think Mom has it right now), and I have a quite pronounced drawl. My mother's mother spoke with a particularly strong Kentucky/country accent, so that's probably where I got it from. I also tend to start subconsciously mimicking other strong accents if I'm around them for a particularly long period of time. (I was told by family that I picked up a very little bit of a Northern Ohio accent while I was working in Cleveland, but it disappeared shortly after I returned home to stay.)
