Auditory event detection for clean speech. (a) Neural activity pattern (NAP) of a male vowel. (b) NAP after group delay compensation. (c) Temporal profile of the compensated NAP in the region below 1.5 kHz (solid line). The dashed line is a threshold used to identify peaks; the circles and vertical lines shows the estimated event times.
