His lips moved, but he said nothing for a long time.

His lips moved, but I could not hear what he said.

I saw the lower half of his face as the lips moved.

Look into my eyes, her lips did not move, the words were in his head.

His lips wouldn't move to give voice to the words.

His lips were moving, though no sound came from them.

His lips were moving, but at first no sound came.

Her lips moved just a little but she didn't say anything.

His lips moved, as though he were talking to himself.

His lips moved, saying something other than what he thought.
