Figure 16From: Efficient voice activity detection algorithm using long-term spectral flatness measure Accuracy and error rate comparisons for five VAD schemes averaged over 12 noises for five SNRs. Accuracy rate: CORRECT, HR1, and HR0; error rate: FEC, MSC, OVER, and NDS. Five VAD schemes: AMR1, AMR2, G.729B, LTSV, and LSFM. Five SNRs (−10, −5, 0, 5, and 10 dB).Back to article page
