Fig 1. Group mean performance in Korean consonant recognition.

Data represent the average of all 11 subjects. In the left panel, consonant recognition scores are plotted as a function of the number of channels, with different lines representing data for different lowpass cutoff frequencies (Hz) as indicated in the figure legend. In the middle panel, consonant recognition scores are plotted as a function of the envelope lowpass cutoff, with different lines representing data for different numbers of channels. In the right panel, contours filled with particular colors represent certain levels of performance (see color bar on the right) as a function of number of channels (abscissa) and lowpass cutoffs (ordinate).
