the Transatlantic Accent from 1940s actors is a whole thing in the world of linguistics but I noticed a modern day equivalent is definitely what I’d call Sportcasters Voice. How every baseball announcer stresses weird syllables. How comedians can adopt it onstage and immediately the audience knows the impression.
