What is the local pronunciation of Chicago? (specifically the 'a')
The standard American English pronunciation is
or (what I think) is the PALM or LOT lexical sets in AmE.
[Here are some examples of many different people (AmE and others) saying 'Chicago]( https://forvo.com/word/chicago/#en)
The very first example, "Pronunciation by themediacollective (Male from United States)" is what I would think is a very different, very local variety of its pronunciation. Matt3799 and TurtlePoser have this same 'a' but not as strong. Mattpsy and Tory1417 have what I think is the standard version (what I think is US typical).
But what is this special vowel exactly. It doesn't sound like /æ/ TRAP to me even though it is in that direction. The most articulate I can put it is that it is ... annoying. An annoying 'a'.
So what exactly is this 'a'? Is it /æ/ or something else? Does this go with other vowel changes (that I just haven't noticed in this same variety)? Is this one example of Northern Cities Vowel Shift
Note: I'm not suggesting that everyone in Chicago says it this way (I'm sorta suggesting quite the opposite, that few do this even in Chicago)
