Spoken natural language dialog systems : a practical approach /
This book addrsesses the dialog issues that must be resolved in building effective spoken natural language dialog systems. The authors present an architecture for dialog processing for which an implementation has been constructed that exhibits a number of behaviours required for efficient human-mach...
