Henry Higgins, Look to Your Laurels
Courtesy of the New York Times you can take the Harvard Dialect Test which will tell you, and I quote, "the pattern of your dialect". You can find it here.
I took the thing. It said I speak like a resident of Salt Lake City, Utah, Grand Rapids, Michigan, and/or Milwaukee, Wisconsin. I speak least like a Bostonian.
Now, I have only spent about 4 hours in Boston and that was in Logan Airport last May changing planes on the way back to California. And that's it. So they got that right. Otherwise. . . .
On the way to Calgary, I once spent about 45 minutes changing planes in Salt Lake City (I never saw so may cowboy hats in my life).
I was driven through Milwaukee once when I was eleven or twelve.
I have never been in Grand Rapids, or indeed the state of Michigan, in my life.
Harvard, you say?
