The advances in computing and networking have sparked an enormous interest in deploying automatic speech recognition on mobile devices and over communication networks. This book brings together academic researchers and industrial practitioners to address the issues in this emerging realm and presents the reader with a comprehensive introduction to the subject of speech recognition in devices and networks. It covers network, distributed and embedded speech recognition systems.

In the last decade the remarkable advances in computing and networking have sparked an enormous interest in deploying automatic speech recognition in devices and networks, and the trend is accelerating.

This book brings together leading academic researchers and industrial practitioners to address the issues in this emerging realm. It covers networked, distributed and embedded speech recognition systems, which are expected to co-exist in the future. The book is divided into four parts: networked speech recognition, distributed speech recognition, embedded speech recognition, and systems and applications. A profound and unified introduction about this area and its latest development is provided, as well as working knowledge needed for research and practical application deployment. This book covers the most up-to-date standards and a number of systems.

This all-inclusive reference is an essential read for graduate students, scientists and engineers working or researching in the field of speech recognition and processing.

Provides a profound and unified introduction about the topic and its latest development Presents working knowledge needed for research and practical application deployment Broad coverage spanning from networked, distributed to embedded systems, which are expected to coexist in the future Covers the most up-to-date standards and a number of off-the-shelf systems
