• Speech coding is a highly mature branch of signal processing deployed in products such as cellular phones, communication devices, and more recently, voice over internet protocol
• This book collects many of the techniques used in speech coding and presents them in an accessible fashion
• Emphasizes the foundation and evolution of standardized speech coders, covering standards from 1984 to the present
• The theory behind the applications is thoroughly analyzed and proved
