Abstract

This paper describes STIS, an intelligent telephone-based spoken dialogue system providing the best traffic route between two sites in Shanghai for drivers and bus transfer information for travelers. STIS integrates automatic speech recognizer (ASR), language understanding, dialogue management, and speech generator. Moreover, STIS performs a deeper analysis by integrating an efficient robust parser and a efficient semantic interpreter. This paper also gives an evaluation of performance of STIS. The dialogue efficiency is 4.4 sentences per query in average and the case precision rate of language understanding module is up to 81%.
