Abstract

This paper describes results of an experiment with 9 different DARPA Communicator Systems who participated in the June 2000 data collection. All systems supported travel planning and utilized some form of mixed-initiative interaction. However they varied in several critical dimensions:(1) They targeted different back-end databases for travel information;(2) The used different modules for ASR, NLU, TTS and dialog management. We describe the experimental design, the approach to data collection, the metrics collected, and results comparing the systems.
