From the Back Cover
A thought-provoking look at the historical and practical evolution of speech coding

Speech coding has evolved into a highly important branch of applied signal processing, resulting in an explosion of products such as cellular phones, answering machines, communication devices, and most recently, voice over Internet protocol. Because of the increasing demand for speech communication, speech coding technology has captured more and more attention from the research, standardization, and business communities–all of whom have been encouraged to pursue and investigate alternative coding methods with the objective of minimizing its deficiencies and limitations.

Covering standards from the inception of digital communication, Speech Coding Algorithms: Foundation and Evolution of Standardized Coders compiles many of the complex techniques widely used in speech coding and presents them in a logical and accessible fashion. By understanding the principles, performances, and limitations of the most successful standards developed throughout history, practitioners will be able to gain sound insights of widely adopted methodologies, with the ultimate goal of developing the next generation of improved algorithms.

A strong pedagogical format makes this text a valuable resource for professionals and students alike.

• Theories behind each application are thoroughly analyzed and proven
• A clear, simple writing style makes complex material easy to understand
• Abundant charts and illustrations help to clarify ideas discussed
• End of Chapter summaries, exercises, and references help to cement understanding and encourage further study

Speech Coding Algorithms: Foundation and Evolution of Standardized Coders is an invaluable textbook for students and researchers eager to enter the speech coding arena, providing a solid theoretical foundation as well as directions for further research. For professionals working in industry who need to access information regarding the many popular standards, the book represents a one-stop reference where the architecture, bit allocation, computational complexity, and operational aspects are thoroughly explained. Among the standards covered are:

• FS 1015 LPC
• TIA IS54 VSELP
• ITU-T G.728 LD-CELP
• ITU-T G.729 CS-ACELP
• ETSI GSM 6.10 RPE-LTP
• FS 1015 CELP
• TIA IS96 VBR-CELP
• FS MELP

Customer Reviews

A jump-start
Reading the few introductory chapters, I discovered that this is an easy-to-read book that covers an interesting and evolving area of research. It provides the reader with a "jump- start" to the area of speech coding. Detailed explanations, with a large number of schematics and illustrating diagrams, furnish a vehicle for a fast learning curve.
Nevertheless, the quality of some of these schematics and diagrams need to be revised in future editions. Furthermore, there are some missing notations with some of the curves discussed; such as in Figure 1.14. I would be happy to see the word (Absolute Threshold in dB) on the vertical axis and the (Frequency in Hz) on the horizontal axis instead of AT (f), f.
In spite of these anomalies, I found the book to be deserving of esteem and respect. For me, the most interesting chapters were those covering linear prediction, PCM, algebraic CELP and speech quality assessment.

Can be considered "the rationale" for speech coding standards
This books serves as an excellent bridge between speech coding standards and speech coding research publications. It does not seek to cover every existing topic in speech coding, but presents analysis and background of some of the most successful speech coding standards. Many "whys" that come to mind reading those standards are addressed. Carefully compliled illustrations accompany almost every important concept presented. This makes cover-to-cover reading of this book a pleasure.

This is a comprehensive book on speech coding
This is a very good book on speech coding, especially focus on CELP coders. Many kinds of CELP coders are introduced in detail. If you are beginner on speech coding, this book is for you. But other coders, such as MBE and WI, are not presented. So I don't think it is a comprehensive book. I give it 4 stars.
