In some ways, it’s a shame that language is organic and evolves, because it means you really can’t roll back pronunciation to an earlier state. It’s still interesting to hear, though, and here’s a story about an effort to reconstruct the pronunciation of Shakespearean English.
The accompanying article explains some of the difficulties and ambiguities in trying to work out the way language was spoken — some are saying it would have sounded more like American English, others talk about Scots/Irish accents. In my ignorance, I’m going to lobby for a more Northern Minnesota version of Shakespearean English. I want to hear MacBeth in those Fargo accents.
