Speech Recognition Over Digital Channels (PDF)

Automatic speech recognition (ASR) is a very attractive means for
human-machine interaction. The degree of maturity reached by speech
recognition technologies during recent years allows the development
of applications that use them. In particular, ASR shows an enormous
potential in mobile environments, where devices such as mobile
phones or PDAs are used, and for Internet Protocol (IP)
applications.

Speech Recognition Over Digital Channels is the first
book of its kind to offer a complete system comprehension,
addressing the topics of distributed and network-based speech
recognition issues and standards, the concepts of speech processing
and transmission, and system architectures and robustness.

Describes the different client/server architectures for remote
speech recognition systems, by means of which the client transmits
speech parameters through a digital channel to a remote recognition
server

* Focuses on robustness against both adverse acoustic
environments (in the front-end) and bit errors/packet loss

* Discusses four ETSI standards for distributed speech
recognition; the understanding of the standards and the
technologies behind them

* Provides the necessary background for the comprehension of
remote speech recognition technologies

This book will appeal to a wide-ranging audience: engineers
using speech recognition systems, researchers involved in ASR
systems and those interested in processing and transmitting speech
such as signal processing and communications communities. It will
also be of interest to technical experts requiring an understanding
of recognition over mobile and IP networks, and postgraduate
students working on robust speech processing.
