1. A method for exploiting information in an utterance for dialog act tagging, the method comprising: receiving a user utterance; computing via a processor at periodic intervals at least one parameter in the user utterance; quantizing the at least one parameter at each periodic interval of the periodic intervals; approximating conditional probabilities using an n-gram over a sliding window over the periodic intervals; and tagging the utterance as a dialog act based on the approximated conditional probabilities.

The method of claim 1 , wherein the conditional probability is further approximated based on a length of the utterance.
