Skyrim: What's the Console Command for Infinite Shouts?

[Eirys]

Saw it here before, can't find it on google.

(You mean no cooldown, right) There's an Actor Value for the Shout cooldown reduction... so, try the following

player.modav ShoutRecoveryMult 0

That should set your cooldown reduction to 100%

edit: Sorry, it's setav not modav
So:
player.setav ShoutRecoveryMult 0
