The Mouth of Sauron

[Kuruharan]

Hmm...I have not looked at this thread in a little while, well, okay, a long while.

Sauron could not talk to living men. (At least after he had lost the ring.)
So, he needed someone to communicate with his troops/ anyone who had business with him.

Why not? I thought that we had already established that he had a body. If he had a body one would presume that he had a physical mouth of his own.

Having the Mouth (as opposed to a mouth) was probably a status thing to reinforce the view of his divinity. Deities are too busy with other things to actually bother speaking themselves to their minions. (Especially when they are not really deities but are desperately trying to impress people that they are.)

I can't remember any scene in LotR where Sauron talks openly. Any views on that?

We have a grand total of one scene where he obliquely appears. I don't think that one could limit Sauron's communication abilities based on the palantir scene.
