The ETSI AMR-2 VAD is rigorously evaluated in clean and noisy conditions. The VAD is then simplified and optimized for porting to an ultra low-resource DSP system using a fast oversampled DFT filterbank. The parameters of the low-resource VAD are optimized using two speakers and 6 types of noise at SNRs from –10 to 20 dB. The VAD is then tested by employing(More)
