I know lots of people who talked pretty much like that growing up.
As for it being original Elizabethan English....yeah, not so much. If you’re interested, there is an outfit in London that has resurrected the pronunciations of the time and actually performs plays in the Globe Theatre using the original pronunciation of Shakespeare. The closest thing it sounds like is like a pirate. But as they note, practically every English speaker in the world, and many with the older dialects will find lots in common with it because it is literally the mother tongue.
I remember old people when I was a kid who still things like p-I-son with a long I instead of poison.
