Table 7 SNR-based relative percent EER reduction rates for i-vector method compared to Drugman’s VAD (second and fourth column) and Rangachari’s method (third and fifth column). Computed by averaging over all noise types

From: A robust polynomial regression-based voice activity detector for speaker verification
