Table 4.

Confusion matrix of consonant decoding for overt speech. The column labels correspond to the predicted consonants pair in a given trial. The row labels correspond to the correct consonant pair. The values in each cell give frequencies in percent and the standard deviation calculated across subjects. This table represents a composite of frequencies derived from all 126 combinations of 4 of nine consonants. The best consonant pair (R_D) is marked in red.
