TI Auditorium


Session Abstract:This talk begins with an overview of packet voice telephony. The key facets of this technology are also briefly presented.
We then focus on voice quality and examine some of the different governing factors. We primarily consider the signal processing layer in this talk, since this layer is generic and is hardly affected by the actual packet voice transport medium. The impact of functions such as voice codecs, silence suppression, echo cancellation, packet loss concealment, etc. is discussed.
A few trends for the future are highlighted.
