We encourage you to try out our dialog system. Your profile information is strictly confidential and will only be used to guide the dialogue system into making reasonable actions to your travel requests. It also allows you to receive emailed itineraries. If you are a registered user, you can update your profile at any time. The system combines continuous speech recognition, natural language understanding and flexible dialog control to enable natural conversational interaction by telephone callers to access information about airline flights, hotels and rental cars.
Users call the system on the telephone and make travel plans for a modeled set of cities .
We are using the system as a testbed for conversational system technology development. For this system, we developed a new Dialog Manager using an event driven strategy. Our natural language and dialog specification for the task is very much declarative. Our approach to robustness in natural language understanding is to use robust parsing strategies and event driven dialog strategies. These strategies stress semantic content and coherence over syntactic form.
