Maybe at CUNY that's in the curriculum lol
Wait! Surfers and pot smokers aren't American? Ahh they may say it with a California accent like "surfs up, brah". Not exactly grad school material
Certainly is! Oddly enough when I studied French at CUNY - (and I was very good at French having started it at age 5 and gotten very high scores on my SATS) I listened to some classmates from the Bronx -speaking in thick Bronx accents - complaining about the accents from Brooklyn! Yet when I went to the ADVANCED French class with them, they had perfect French accents!
Just as an aside - I am always stunned to learn that some of the most famous US TV actors were actually British = like Hugh Laurie who played Dr. House.
I can speak in Very Respectable "North Carolina Mountain" - but can not discern the difference between the Bronx and the Brooklyn accent.
Once I met a man our local "watering hole" who spoke in a thick NYC accent. I learned he was French and switched over to that language. In English, he sounded like a "street worker" - as in - a bad accent and improper grammar. But in French, he sounded like a University Professor... so I told him that... and he was Stunned! "How can I fix that?" I told him to watch the movie "My Fair Lady"
