"This book is the first to focus exclusively on this growing topic. It begins with basic coverage of typical approaches used in SLU, such as favourite classification methods and modeling techniques, and discussion of the terminology used. It then provides state of the art approaches for the application of SLU in both human/human communication, and spoken dialog systems"-- Provided by publisher.
