Figure 5From: The Effect of a Voice Activity Detector on the Speech Enhancement Performance of the Binaural Multichannel Wiener Filter Intelligibility weighted SNR improvement for directional speech-shaped noise at different SNRs for perfect VAD and envelope-based VAD with β = 0.1, 0.2 and 0.3. (a) λ = 1 and (b) λ = 0.8 . Back to article page
