I don't know if this is an English-only thing or not, but the emphasis on a particular word in a sentence can convey some extra info.

Ex: He's not lying.

1. He's not lying. (Someone else is lying)

2. He's not lying. (Same as original but more forceful)

3. He's not lying. (Depending on context, could mean "He's not technically lying, but perhaps I'll agree he's stretching the truth a little.", or it could mean "OMG c'mon this is Jim we're talking about, he's not LYING...are you crazy? He always tells the truth."

I wonder how many court transcript readings have totally screwed someone over because of something like this. Add sarcasm to the mix to take it up a notch.
