Sommario/riassunto

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 protocolThis book collects many of the



techniques used in speech coding and presents them in an accessible fashionEmphasizes the foundation and evolution of standardized speech coders, covering standards from 1984 to the presentThe theory behind the applications is thoroughly analyzed and proved
