From the reviews: "In this book, the authors describe their approach to OwlSpeak, an adaptive spoken dialogue manager (ASDM). It is intended to be a spoken interface to intelligent environments in the context of real-life situations. ... we found the book very valuable in providing an overview of the fundamental challenges with SDSs, approaches toward the realization of such systems, and a framework for the evaluation of spoken dialogue managers."
