An old man turned ninety-eight
He won the lottery and died the next day
It's a black fly in your Chardonnay
It's a death row pardon two minutes too late
Isn't it ironic ... don't you think
"Oh, a sarcasm detector. That’s a really useful invention!"

“YEAH RIGHT”: SARCASM RECOGNITION FOR SPOKEN DIALOGUE SYSTEMS (PDF)
Joseph Tepperman, David Traum, and Shrikanth Narayanan
The robust understanding of sarcasm in a spoken dialogue system requires a reformulation of the dialogue manager’s basic assumptions behind, for example, user behavior and grounding strategies. But automatically detecting a sarcastic tone of voice is not a simple matter. This paper presents some experiments toward sarcasm recognition using prosodic, spectral, and contextual cues. Our results demonstrate that spectral and contextual features can be used to detect sarcasm as well as a human annotator would, and confirm a long-held claim in the field of psychology – that prosody alone is not sufficient to discern whether a speaker is being sarcastic.
