Speech Coding for Voice Over IP and Wireless Communications
by
Alan V. McCree (Texas Instruments, Inc., USA)
Juan-Carlos De Martin (Polytechnic University of Turin, Italy)

Abstract

     Speech, once predominantly transmitted on circuit-switched networks, is now conveyed through a multitude of communication channels, ranging from wireless (cordless, cellular, and satellite) to packet networks (IP, ATM, and Frame Relay). How are these new transmission media affecting the way we understand and design speech coding solutions?

     This tutorial will offer an overview of speech coding, with emphasis on both fundamentals and applications. We will cover the key features of modern speech coders, and discuss the technology that has enabled the remarkable advances in this field. Finally, we will focus on wireless communication and packet network applications and address the key question: what perceptual quality is achievable right now, under what assumptions, ----and at what price?
