Did the Ring speak on Mount Doom?
I think it did. It all comes from two paragraphs.
"Then suddenly, as before under the eaves of the Emyn Muil, Sam saw these two rivals with other vision. A crouching shape, scarcely more than the shadow of a living thing, a creature now wholly ruined and defeated, yet filled with a hideous lust and rage; and before it stood stern, untouchable by pity, a figure robed in white, but at its breast it held a wheel of fire. Out of the fire there spoke a commanding voice.
'Begone, and trouble me no more! If you touch me ever again, you shall be cast yourself into the Fire of Doom.'"
Maybe Sam was delirious after crossing the plain of Gorgoroth and all of Mordor. The description does fit well with his ideas of Gollum and Frodo. But I do not think he had gone long enough without food and water to be that far out of his mind.
Frodo himself said that he saw the ring as a wheel of fire before turning away from the Orc-road.
"I am naked in the dark, Sam, and there is no veil between me and the wheel of fire. I begin to see it with my waking eyes, and all else fails."
That they both saw the same thing seems to support the vision. But maybe the fact that Frodo called it a wheel of fire in front of Sam takes away from the vision, as it could have been unconsciously remembered and brought forth.
A rather simple answer to whether or not the Ring spoke is no, of course not, inanimate objects don't run around talking to people. But the Ring speaking on Mount Doom is not the only time it has happened.
At Cabed-en-Aras in the First Age Gurthang, the sword of Turin Turambar and Beleg Cuthalion before him spoke aloud.
"And from the blade rang a cold voice in answer: 'Yea, I will drink thy blood gladly, that so I may forget the blood of Beleg my master, and the blood of Brandir slain unjustly. I will slay thee swiftly."
If an elvish sword can speak, can not a ring containing the greater part of the power of a god?
