System and method of exploiting prosodic features for dialog act tagging in a discriminative modeling framework |
摘要 |
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.
