Third Recommendation: I can suggest that you listen to recordings of famous speeches to prepare yourself and there are many of such recordings. Those can be regarded as "slow" speech. Recommendation Two: In general, you could listen to TED LECTURES and practice with those. http://www.ted.com/talks Recommendation One: Listen to the recorded Debates between William Lane Craig and Sam Harris and between William Lane Craig and Peter Atkins, and also the Debates between John Lennox and Richard Dawkins. Practice with the latter, and your vocabulary will be advanced to a high academic level.
