The book is designed for Engineers, market managers, product managers, wireless network managers, and students of telecommunications technology. The book is unique in the sense that it tries to explain concepts, algorithms and methodologies without resorting to complex math. It addresses voice codecs, electric and acoustic echo, noise and noise reduction, level and automatic, adaptive level control, network problems, their resolution, and network management issues. Cambridge University Press, the publisher, has linked recordings -- I provided as examples to many voice issues described in the text -- on their web site.

5 stars -- A great book for Engineers working in this field, March 8, 2009

I was introduced to this book by my colleague. He lent me a copy he had. I was an engineer in audio/acoustics who started to work in the mobile telephony field. I found a wealth of information in the book, and found the book easy to read at the same time. No high-brow, difficult to read writing at all.

I bought my own copy shortly after. I read this book again just prior to my interview with my present employer. It certainly helped me landing my job! This is an excellent book, and I heartlily recommend all who are working in this area.

5 stars -- Great practical review of telecom voice quality issues, June 28, 2007

(REAL NAME)
Dr. Perry has written a great reference on voice quality issues found in real-world telecom networks. This book goes beyond the "can you hear me now?" level of network voice quality. His careful coverage of voice quality concepts will allow newcomers to grasp the key essentials. Sufficient references are provided to allow a "deeper dive" into more technical details if required. The book's website offers several audio WAV files to demonstrate the concepts presented in the book. He assesses the risks to voice quality with the migration to IP based voice transport.
