We hear 6 speakers of standard English from different areas: Smithfield Virginia, Green Bay Wisconsin, Brooklyn New York, North Andover Massachussets, and Dallas Texas. I've never heard of some of the dialect features demonstrated in this film, and think they must have been lost by the current day.
It's too bad the speakers here are only asked to repeat single words and simple phrases, it would be interesting to hear longer dialogues.
It also looks like it was live and unrehearsed, and sometimes the guests don't give the answer the host/linguist expects! Presented by linguist Henry Lee Smith Jr.
