Ah, interesting.
What gets me is how I grew up hearing “coyote” pronounced as “ky-OH-tee” but then I hear some people, perhaps from the west, say “KY-oat”.
(Barbara Cameron’s RR Theme song):
Road runner, that ky-oat’s after you
Road runner, if he catches you you’re through.
(somehow doesn’t seem the same that way!
I grew up in California, saying "ky-oh-tee." My husband, from Utah, says "ky-oat."
I think that, as a result of living most of my adult life in Maryland, I do not have a specific regional accent. In both CA and MD, people ask me where I'm from. Now I live in TX, and no one asks me that. I only know one person with an obviously Texan accent; everyone else has the "generic" accent peppered with mild regional flavors hinting at their true origin.
C. J. Box writes current-day westerns about Wyoming, and he has funny stuff about how people from outside the state dress trying to look western and affect phoney western accents. Another dead giveaway is that they say cy-o-tee when everybody knows it’s coy-ote.
