The best one I heard was when my son was fishing on the Stubblefield bridge on the North fork of Lake Conroe in Walker County. He said this old lady pointed to the creek bank and said, “I’m gonna bunker down over yonder.”
That would have been “hunker down” not bunker.
Anyway, I think Texas has two accents, the more nasal one from East Texas especially in women and a western one. My father in law sounded like actor Ben Johnson. Overall though, American accents seem to be fading.
