Figure 6.
The effect of the number of filters and N on the temporal correlation between a vocoded word-in-noise and the control word in quiet. This is the same analysis as in Figure 5C, except that different number of filters were used in the vocoder: (A) 20 filters; (B) 5 filters; (C) 1 filter. Note that each panel has two abscissa scales: the top scale (in red font) is the number of samplers per channel (N); the bottom scale denotes the total number of samplers (NTOTAL) obtained as the number of filters times N. Note also that N varied across the three panels while NTOTAL remained identical. Note also that NTOTAL was identical as in Figure 5.
