Paper Abstract

Although speech coding has been an ongoing area of research for several decades, the recent advances in real-time DSP and the emergence of new applications have spurred a renewed interest in the area. Several speech coding algorithms have been adopted in international standards and study groups are drafting new standards for existing and emerging mobile and multimedia applications.

In this paper, we provide a survey of speech coding technologies with emphasis on those methods that are part of recent communication standards. The paper starts with an introduction to speech coding and continues with descriptions of linear predictive vocoders, analysis-by-synthesis linear prediction, sub-band and transform coders, and sinusoidal analysis-synthesis systems. We conclude with a summary of this critical review paper along with a brief discussion on opportunities for future research.
