- Offers
a unique presentation of the basics of speech coding and the
innovations that make coders useful and efficient
-
Describes the fundamentals of auditory information processing
and how they relate to speech coding
-
Shows how to evaluate the strengths and weaknesses of all publicly
available codes
-
Explains how to measure the quality of speech coders with objective,
subjective, and perceptual measuresconditions
The
demand for digital speech coding algorithms grows every day, fueled
by applications such as streaming speech over the Internet, Internet
telephone, digital cellular telephony, wireless teleconferencing,
and various multimedia applications. Until now, most of the books
available on audio coding have been collections of individually
authored papers. Others have discussed the fundamental coders,
but neglected many of the innovations currently in use. Unlike
these books, A Practical Handbook of Speech Coders offers in-depth
treatment of the basics of speech coding plus the innovations
to the basic methods that make the coders useful and efficient.
The authors designed this work for engineers, scientists, and
manager who need to understand the emerging speech coding techniques
and telecommunication standards. However, it will prove useful
to people at all levels of speech coder experience:
o If you want to simply download the code for an existing algorithm,
this book helps you evaluate the strengths and weaknesses of all
publicly available codes and choose the right one, then points
you to the Internet location where the code is available for download.
o For experts who want to improve on existing coders, this book
provides the parameters of current coders and the techniques to
improve upon them. You can download an existing algorithm or code
it using the algorithmic descriptions in the book, make your innovations,
and then test the code with the procedures given.
o If you want to become an expert and have some basic knowledge
of digital signal processing, you can learn the innovative steps
taken by the inventor of each coder, explore the rigorous research
techniques needed to develop your own coder, and become proficient
in existing vocoder technology. |
