Somehow I never thought of him speaking with talk that I could understand. It makes his death seem even more horrible.
Also when they talk about how the sound of the words has changed is that the 'vowel shift'? Or had that happened already, before him?
Also, as a US person I would not know 'West Midlands' if it hit me on the head. I can tell a guy who sounds like a young Michael Caine, from a guy who sounds like Hagrid. Neither sound like recordings of the Queen. (I am always surprised by how high and squeaky her voice is, but that is not accent so much as voice box I think.)
Anyway-- I suppose this is not really science, but it is cool.
And I think anything that makes any history nearer is a good thing.
