Paul Meier and other scholars of the history of the English Language have reconstructed what they believe to be the way in which English words were pronounced during the time of Shakespeare. He's staging a production of "A Midsummer Night's Dream" next month in that original pronunciation:
“American audiences will hear an accent and style surprisingly like their own in its informality and strong r-colored vowels,” Meier said. “The original pronunciation performance strongly contrasts with the notions of precise and polished delivery created by John Gielgud, Laurence Olivier and their colleagues from the 20th century British theater.”
The above video is a sample of the original pronunciation.
