Here is a great collection of maps based on pronunciation of words and phrases. When I moved to the Midwest after growing up in the Northeast, I was often made fun of for saying “hoagie” instead of “sub,” “soda” instead of “pop,” and “crown” instead of “crayon.” (OK, that last one is a bit weird, I admit).

Update: The link no longer works (probably from the huge increase in traffic from this site. . .). I’ll update again if the site comes back.

Update: I asked Dr. Bert Vaux, the creator of the survey, why the results were taken down. He is now working on a new study at Cambridge. The site is in a pilot phase and requires registration to view the results.
