The NY Times:
The online Yellow Pages includes more than a dozen listings for “New York accent reduction” specialists, and searching “New York accent” and reduction or elimination on Google generates about 4,000 hits. The process typically takes at least several months, with as many as three sessions a week, and can cost from a few hundred to a few thousand dollars.
It's been so many years since I left that few people in the Midwest think I'm from New York, but they do generally peg me to the East Coast.
But this quiz identifies my accent as Inland North:
You may think you speak "Standard English straight out of the dictionary" but when you step away from the Great Lakes you get asked annoying questions like "Are you from Wisconsin?" or "Are you from Chicago?" Chances are you call carbonated drinks "pop."
Yes, because when I say 'soda' people have no idea what I'm talking about.
This longer quiz, identifies my accent as Northeastern:
This could either mean an r-less NYC or Providence accent or one from Jersey which doesn't sound the same. Just because you got this result doesn't mean you don`t pronounce R's.(People in Jersey don`t call their state "Joisey" in real life)
Anywhere from New Jersey to Providence? There's a lot of accent wiggle room in there, but I did, in fact, grow up in places between New Jersey and Providence.
