Apparently I do, at least according to these maps of American dialect and pronunciation.
My pronunciations are most likely to be like New York City (where I was born, but moved away to DC at age six) but several of them are not. Although I spent five years in the UK, and hang around a Brit a great deal, I don’t think I have (m)any English pronunciations, although I may have the odd bit of British slang.
Interesting, but I want to know more about his data. Some of the usages strike me as really not quite English as she is spoke. At least not in my experience.
