I've been listening to a section of The Great Courses: Medieval History, an audiobook narrated by Kenneth W. Harl. From his accent, Prof. Harl is clearly American, with what I would describe as a standard Midwestern accent (TV announcer variety) except for a few quirks here and there.
One of the quirks is his penchant for pronouncing warrior as if it rhymed exactly with lawyer, i.e., ˈwɔ yər. This pronunciation seems not to be accepted in dictionaries, as the various listed pronunciations I find include ˈwɔr i ər, ˈwɔr yər, ˈwɒr i ər, ˈwɒr yər. His Wikipedia page gives no mention of his origins.
I believe I've heard this pronunciation before, but I can't place it and if my memory serves it seems rare to me.
Is this a feature of a dialect, idiolect, or something else? If a dialect, which one(s)?
