You have to shout at a living enemy. If you kill the enemy with the shout, not only will you capture their soul (like a soul trap spell or weapon), but the fallen enemy will be raised like a reanimate corpse spell. There's no level cap, as far as I've been able to determine. I killed a giant with it, and he raised up and murdered my foes just fine.
Edit: If you don't kill the enemy with the shout, but kill them while they're still glowing blue, you just capture the soul, and they don't get reanimated.
