Dr Ether over at Ethercast fired us an email to let us know that he's finished his Meet the TF2 Voice Actors! playlist, containing 35 minutes of amazing footage covering the many roles that TF2's voice actors have held in the past. Note that there's some strong language in there, so you might want to avoid the Scout & Medic videos if that's not your cup of tea.
