The “Circuit Fix-it Shoppe” is a voice interactive dialog system which has been constructed in our laboratory. The mission of the system is to help people repair electronic circuits. The system contains a domain modeler, a reasoning system, a dialog controller, a user modeling system, an error-correcting natural language parser, and a natural language generator. A commercial speech recognizer and speech synthesizer are used for voice input and output. More detailed information about our dialog system can be found in [l] and [2]. This videotape records two live dialogs between the Circuit Fix-it Shoppe program and a user who has no special knowledge of computers, electronic repair, or our system. A brief description of the experimental setup and of the Circuit Fix-it Shoppe program precedes these dialogs.
