摘要: Algorithms for voice activity detection in the presence of vehicular noise and babble are presented. The detector (VAD) designed is an improvement upon VAD adopted discontinuous transmission (DTX) mode GSM standard, performs significantly better at low SNR levels. Work on a that suited environment also briefly mentioned, scheme combining two VADs proposed.
