Since there were no voice-over training missions packaged with LOMAC and no voice-over training missions packaged with Flaming Cliffs, I would guess that this is yet another screwup by Evolved Games.
I'm just guessing, though. If you are getting text boxes describing what to do, you are getting all that the rest of us got the first time around. The only missions with voice-over that I know of are third-party and not included with the product.
