CELP SPEECH CODING FOR VOICE-OVER-IP COMMUNICATIONS

摘要

VoIP is one of the buzzwordsrnin the communicationrnindustry at the moment. DavidrnMann discusses a virtualrncomponent solution for thernG.723.1 standard.rnThe provision of toll-quality voice telephonyrnover packet-based networks -Voice-over-Internet-Protocol systems, for example - is critical to the convergence of voice and fax traffic with other data communicationsrnservices. The front-runner speech coding algorithms for packet-based telephony are based on a technique called Code Excited Linear Predication (CELP).
