Training and Evaluation of a Spoken Language Understanding System

This paper describes our results on a spoken language application for finding directions. The spoken language system consists of the MIT SUMMIT speech recognition system ([20]) loosely coupled to the UNISYS PUNDIT language understanding system ([9]) with SUMMIT providing the top N candidates (based on acoustic score) to the PUNDIT system. The direction finding capability is provided by an expert system which is also part of the MIT VOYAGER system [18]).
