Interestingly the New Orleans accent isn't a southern accent at all, it sounds more like Brooklynese... when talking to NOLA natives they sound like they're from New York to the untrained ear. This is because NOLA had a lot of the same immigrants as NYC. And this is a different accent than the Louisiana cajun accent.

But I do remember that Sammy the Bull said he met with the underboss of the NOLA family in the late 80s and he said he couldn't understand a word he was saying, so no idea lmao.
