Ignoring the linguistically incorrect and wrong-headed things said in this video, the more puzzling problem: I have no idea what dialect or type of English the man in the video is speaking. I have never heard English that sounds like this. I can't even tell whether or not he is a native speaker; his website implies that he is American, but doesn't say outright. Any ideas?
My first impression of Leonard Balazer was that he sounded like a elderly Midwesterner who was over-enunciating. (The "boing-boing" audio compression artifacts don't help matters.)
His Facebook page confirms that Mr. Balazer grew up Saginaw, Michigan, and was educated in and spent his professional career in Michigan.
I have not been able to find any definite information on Professor Balazer other than the linked website, but my best guess is that either he is hyper-pronouncing because he is teaching/coaching pronunciation or else he is hyper-pronouncing due to injury/illness.
