There’s an article in Philadelphia Magazine called “Here’s how millennials are changing the Philadelphia accent” and it’s better than bad – it’s good! The author talks to linguist Betsy Sneller, who was on a recent episode of the Vocal Fries podcast, about her research into the changing Philly dialect. It’s chock full of good linguistic information, a note about how of course millennials are changing the accent (that’s what the younger generation does), and sound files! And somehow they managed to get through a whole article on Philadelphia and language without mentioning jawn. That’s not easy, well done.
