Southern. Reckon ah’ve lost ahll my other flahvahs.
Q re: Q16. It says “oo” like foot or food. I know people who pronounce the “oo” in both identically. Is that a common feature of any US accents?
I’m an English southerner and I got North Eastern too 
Is there some place on the page (I look, but might have missed it) that describes the various accents and tells the region they are from?
I scored neutral. Born, raised and lived my whole live in Northern California, same as my parents.
Unsurprisingly, I’m “neutral.”
People can never figure out where I’m from. They usually guess “east coast,” but that’s only because I’m obviously not from the South.
Having been born and raised in Maryland, and then lived in Pittsburgh during college, and now in Arizona for 30 years, my accent and colloquialisms are an amalgam of all these places.
My wife says I have “radio voice” - but I’m not sure I believe her.
It needs one more question to be sure.
Q: you need to drive between Sacramento and Los Angeles. How do you do so?
A1: I like, you know, take the 5.
A2: It’s hella easy to take 5.
Wikipedia: some parts of the Midland. As I said, I associate it with an older generation.
I’m “neutral”, which is not at all surprising as I’m from Kansas City, which gives me the ISO Standard accent that Walt Disney and Johnny Carson had.
I’ve never heard anyone pronounce “foot” and “food” with the same vowel sound. “Foot” usually has the same sound as “put” and “food” sounds like “rude.” I do hear people pronounce the word “roof” like one or the other, though.
And my accent tested out to be neutral. Which was what I figured, since I’m from Pennsylavania.
Neutral - that’s no big surprise.
How did you guys get “Canadian”? Do you actually pronounce it “aboot?” (I pronounce it “abowt.”) 
Mid-Atlantic. I grew up halfway between Philly and Baltimore so I’d say that’s about right.
The question with bath/pass/staff vs bat/pack/trap kinda threw me off, and when I tinkered a bit, it was the difference between Mid-Atlantic and Northern for me. That’s sort of interesting.
It says neutral but I have a ridiculously Southern accent. But bag rhymes with vague? I’ve never heard that one.
Northern, which is not surprising since I’m from Chicago.
And as I was answering them I’m afraid I’d catch myself wondering who would answer any other way.
Mid-Atlantic. Raised in Western Ny.
It tagged me as** “Northern”**. Mildly surprising to me because I’m from a bit south of the area indicated on the map they showed. I blame my parents. They’re from Chicago.
I’d be interested in seeing all of the different accents and their maps but I couldn’t figure out how to find them on the web page.
The American version of what Brits call Received Pronunciation, i.e. the smooth and nondescript typical “American” midwestern accent. I lapse into slightly more of a West Texas drawl when I’m really relaxed, really tired, or trying to be amusing.
Northern.
Born in the South, Grew up mainly in the Northeast but have lived the last 30 yrs in the South (or de Facto South)
Neutral. Although I’d say with a slight southern drawl. I’ve always said I had a TV accent.
Northeastern. Which is spot on.
In what accent would BAG ever rhyme with VAGUE? (Bayg? Vag?)
Neutral, I grew up in Oregon but now live in Boston. I’ve had locals tell me that they can tell that I’m from somewhere else although nearly all the Americans I work with sound neutral. It’s a class thing (sorry, but it’s true).
