Second and third order adaptable threshold for VAD in VoIP
Reducing the Internet traffic is a requirement to share the bandwidth with many sessions. When circuit switched applications are ported on to the Internet, bandwidth saving becomes all the more prominent. An efficient adaptable threshold VAD (voice activity detection) for voice over IP systems is pr...

| description | Reducing the Internet traffic is a requirement to share the bandwidth with many sessions. When circuit switched applications are ported on to the Internet, bandwidth saving becomes all the more prominent. An efficient adaptable threshold VAD (voice activity detection) for voice over IP systems is presented in this paper. The discussion includes two energy-based algorithms with higher order threshold refreshing schemes. The performance of all the schemes is presented, and the results bring out clearly the usefulness of the schemes for VoIP applications with saving in bandwidth. |
