How do I know if I have the Northern Cities Vowel Shift?

I'm also born and raised in Kalamazoo, MI. From my understanding of NCVS, I don't think I have it (can't entirely decide), but I'm sure my parents don't.

Considering my friend group of people who are from the cities (excluding suburbs) of Chicago, Detroit, and New York (the Bronx), I find NCVS:

  • very noticeable from New Yorkers
  • not at all noticeable from Detroit people
  • somewhat noticeable from Chicagoans

Interesting, since Kalamazoo is the half-way point between Chicago/Detroit.
