Accent game

My particular dialect of English has 12 vowels. That's a little interesting because a) the book I have on American English Linguistics claims most American dialects of English have 9 vowels, and b) because I speak what's pretty close to "American Standard." If you look up English dialects on Wikipedia (the article is actually called List of Dialects of English Language) you'll find a subsection called Midland American English and below that the dialects North Midlands, St. Louis and South Midlands. Though I grew up in the St. Louis region, I don't have a St. Louis accent. That's because it should properly be called a South St. Louis or St. Louis German accent. Only a minority of people in St. Louis talk like that. What I speak is North Midlands. South Midlands is what we used to disparagingly call Ozarkian, Hill Billy, Okie, Appalachian and so forth. It has a distinctive twang to it. It's often heard in "country music." North Midlands these days is the 900 pound gorilla of American accents. You are much more likely a job as a TV announcer if you speak North Midland than any other accent. North Midlands seems to be displacing a lot of the beautiful accents of the South and West, so that much of what you can read about American accents is rapidly going out of date.

At any rate, on to what I really wanted to discuss. Linguists distinguish individual phonemes of a language by what is known as minimal pairs. You change one and only one element of a word and see if you get a different valid word. For consonants you might have something like cat-cap. Not too surprisingly 't' and 'p' represent separate phonemes of English. For the vowels you might have something like mate-mat, where the e is silent and has no effect other than to tell us how to pronounce the letter 'a'. What I think are more interesting are possible minimal dozens. That is a dozen words which form a set of minimal pairs for all of the vowels. Honestly, I don't think there are any. But I can come close. My vowels are long a as in ate, short a as in at, long e as in eat, short e as in ebb, long i as in ice, short i as in is, "schwa" sound as u in up, long o as in oak, short oo as in book, long oo as in moon, short o sound as in odd or father, and finally "aw" sound as in awl or tall. English has a tendency to treat diphthongs like pure vowels. So long i is technically a diphthong, but for historical reasons is validly treated like an English vowel. The "Aw" on the other hand may look like a diphthong in print but it's a pure vowel when spoken. It's very much the short o with more rounded lips.

Take
Tack
Teak
Tech
Tick
Tyke
Tuck
Token (not a minimal pair but, as close as I can come to real word with the same environment)
Took
------ (Place holder for a word with t+long oo+k)
Tock (is it even a word?)
Talk

( More attempts )

Can you come up with a complete set (any combination of consonants) for the vowels in your dialect?
