Technically, that would be a creole.
Please explain. I've got a Creole friend who would most definately disagree. I thought cajuns were from the french acadians? Cajun dialect is unlike anything that I've ever heard. I worked in Iberia and St. Mary's Parish for awhile and it hurts your head trying to keep up with what they are saying.

New Orleans has several different accents that I remember. The most notable was folks from Chalmette, who have almost a Boston accent. Add Uptown with the Leghorn speak and Metarie with the mix of a little of everthing.

Pittsburgh has a distictive nasal quality to the accent (and the word yunz for you guys).

West of the Missippi, you've got several different "drawls" in Texas each marked by a different cadence. Southern Illinois has one that is somewhere between Texas and a country drawl.

I'd have to say that Western North Carolina has the most bizarre (next to cajun) that I've ever heard. A fast nasal whine that's almost impossible to understand.
