Integrating flexibility into a structured dialogue model: some design considerations

Michael F. McTear, Susan Allen, Laura Clatworthy, Noelle Ellison, Colin Lavelle, Helen McCaffery

Structured dialogue models are the most commonly used dialogue models in commercial systems, particularly as they are relatively easy to design and re-use. The current paper reports on a study that examined the feasibility of combining more flexible dialogue control with a structured dialogue model. Several systems were built using the RAD (Rapid Application Developer) component of the CSLU toolkit, augmented with the Phoenix natural language parsing system and a dialogue manager that used a representation of the system’s information state to determine the system’s next question or action. Results indicated that with an optimized continuous speech recognizer a dialogue permitting flexible input can be concluded efficiently and successfully, while in cases of degraded recognition the recovery strategies and more structured dialogue control enhance the likelihood of a successful transaction. The paper discusses a number of design issues that support developers in making structured dialogue models more flexible.
