First Claim
Patent Images
1. A method for exploiting information in an utterance for dialog act tagging, the method comprising:
- receiving a user utterance;
computing at periodic intervals at least one parameter in the user utterance;
quantizing the at least one parameter at each periodic interval;
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.

Abstract
Disclosed are a system and method for exploiting information in an utterance for dialog act tagging. An exemplary method includes receiving a user utterance, computing at periodic intervals at least one parameter in the user utterance, quantizing the at least one parameter at each periodic interval, 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.
