Robust Multimodal Dialog Management for Mobile Environments

This chapter describes three aspects of mobile dialog management: robustness in the presence of recognition errors; dynamic behavior based on user context (e.g. network connectivity, location); and efficient scenario description for multimodal dialogs. We describe algorithmic techniques for these three aspects of mobile dialog management, and results from empirical user studies are discussed which indicate significant improvement in performance and user satisfaction when these techniques are deployed in a dialog system.
