The design and implementation of the AT&T Communicator mixed-initiative spoken dialog system is described. The Communicator project, sponsored by DARPA and launched in 1999, is a multi-year multi-site project on advanced spoken dialog systems research. The main focus of this paper is on issues related to the design of mixed-initiative systems. In addition to describing our architecture and implementation of the complex travel task, the paper reports on some preliminary evaluation results.
