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.
