So, since this first idea for adding voices was started we have actually removed the vast majority of them from the game. I think only 1 or 2 quests currently have any voices. The reason for this is that I've edited, added/removed/adjusted bits, for every quest in the game a number of times, then there are Mordaan's edits on top of mine. As this happens the recorded voices and npc dialogue no longer match, so once that happens we just remove all the voices for that quest.
So the tutorial, this was totally re-written from the version which was voiced, so is no longer voiced.
