Speech Coding and Speech Quality in IP Telephony

Overview Speech codecs compress the voice in such a way as to affect its quality and in turn the quality of service (QoS) delivered by IP telephony systems. The speech encoder converts the digitized speech signal (after A/D conversion) to a bit-stream, which is packetized and sent over the IP network. This paper describes the concept of Speech coding and speech quality in IP Telephony and its benefits. It also briefly introduces the GIS’ speech processing software for IP telephony GIPS Soundware.
