For professional speech researchers, there is a rich technical literature covering many years of primary research in speech. However, this literature is not necessarily applicable to the needs of business people, application developers, and students who are interested in learning about the practical uses of speech technology. On the other hand, while existing introductory resources cover the basic mechanics of development of application development as well as aspects of the voice user interface, they don't go far enough in dealing with the details that have to be taken into account to make spoken dialog systems successful in practice. What's missing is information in between the in-depth technical literature and the more introductory development resources. The goal of this book is to provide information for anyone who wants to take the next step beyond the basics of current speech applications but isn't yet ready to dive into the technical literature. It is hoped that this book will help project managers, application developers, and students gain a fuller and more complete understanding of spoken dialog technology and the practical aspects of developing and deploying spoken dialog applications.
