I know he is stronger than the rest, which is why he can control his speech. The wiki says that he only knows 7 shouts. In-game, maybe. That's all that the developers felt necessary to give to that particular NPC. In the lore, his mastery of the Thu'um is unparalelled. Plus the fact that if he's the most powerfull of the Greybeards can be heard from Ulfric yourself.

If you talk to him before going up to the High Hrothgar for the first time.
