The inferi are actually the corpses that have been re-animated using a spell. They can move (under orders of their controller) but they cannot speak. See Bathilda Bagshot, Deathly Hallows. They are essentially "zombies".

In HP and the HBP, you must kill the Inferi as they come out of the water. If you let them surround you, you will have to replay the scenario over and over.

Watch out on the waves for Inferi who climb faster than the rest. They must be destroyed before they touch you.
