The Waxholm system - a progress report

Abstract

This paper describes ongoing development work on the spoken dialogue system, WAXHOLM, providing information on boat traffic in the Stockholm archipelago. The dialogue control and the natural language parser are implemented in an integrated, knowledge-based probabilistic language model. The recognition process is based on neural nets, A* lexical search, and a candidate reordering module. Speech synthesis for spoken response has been enhanced by the display of a synthetic, animated face. Application-specific data have been collected with the help of Wizard-of-Oz techniques.
