How to Make a Typographical Cake

I'm ~40 miles outside of Newark NJ, which is where it identified me; I'd say it did a pretty good job.

I'm a native Chicagoan, and this tried placing me as being from New York or Boston.

It put me either in Newark or eastern Florida...neither of which accurately represents, in any sense, where I actually live. XD (In fact, I live in the deep Southwest.)
That said, I moved around almost constantly as a kid, and went to school in Missouri, so I've been exposed to so many dialects that I can use 'sunshower' and 'sneakers' on one hand, and then turn around and use 'y'all'.

It put me in Rochester NY. Not bad considering I'm from Syracuse. I think that folks who have moved a lot might get skewed results.

I'm sittin' in Oklahoma City right now, just visitin' fer Chrissmiss, and sher enough, that dang ol' computer predicted that I'm around the Oklahoma City/Tulsa area. Guess that means I've binn here too long.

I'm gob-smacked [closet Anglophile] the map located me between Fresno and Bakersfield [CA]. I always thought Californians didn't have accent/dialect.

The quiz placed my speech from northwestern Georgia. That's reasonable.
