Jim Dale InterviewBooks
AudioBooksToday.com has an interview with Jim Dale, in which he comments on the books, J.K. Rowling, and accents:
My voice now, although its still English, I suppose it had traces of Americanism in it, because living over here you have to use certain words that can only be understood. Its no good saying pavement when you mean sidewalk. Its no good saying lift when you mean elevator. Its no good saying boot when you mean the trunk of a car. Or bonnet when you mean hood of a car. You do have to use a lot of American words that we don't use in England.
Thanks for the link, Charlie!
