The voice of Alexander Graham Bell

Despite the fact his inventions like the telephone have helped billions of people hear others voices (and record voices) no one knew what Alexander Graham Bell's own voice sounded like (apart from people who knew him of course).

Now one of the earliest wax disc recordings from 1885 which comes complete with a written transcript by Bell has been scanned using a non-invasive optical sound recovery process and audio extracted by calculating how a stylus would move through the grooves of the disc. More details of the optical scanning can be seen here.
