Integrating Flexibility into a Structured Dialogue Model: Some Design Considerations

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.
