Figure 6From: Single channel speech separation in modulation frequency domain based on a novel pitch range estimation methodOnset and offset detection. The upper panel shows the response intensity and the lower panel shows the results of onset and offset detection using a low-pass filter. The threshold for onset detection is 0.05 and for offset detection is -0.05 indicated by the dash-lines. Detected onsets are marked by downward arrows, and offsets by upward arrows.Back to article page
