Abstract
In this paper, we describe a prototype spoken language system that loosely integrates a speech recognition component based on hidden Markov models with a constraint dependency grammar (CDG) parser using a word graph to pass sentence candidates between the two modules. This loosely coupled system was able to improve the sentence selection accuracy and concept accuracy over the level achieved by the acoustic module with a stochastic grammar. Timing profiles suggest that a tighter coupling of the modules could reduce parsing times of the system, as could the development of better acoustic models and tighter parsing constraints for conjunctions. 1. INTRODUCTION In this paper, we describe a prototype of a spoken language system that integrates a speech recognition component based on hidden Markov models with a constraint dependency grammar (CDG) parser. The underlying goal of our combined system is to identify the 'best' overall sentence candidate with respect to all available knowledge s...
