Modeling the impact of cochlear nerve degeneration on speech recognition performance
Fig 5
Confusion matrices for word classification across simulated CND.
Each matrix summarizes predictions for 25 NU-6 words (65% time-compressed, 0.3-s reverberation) presented at 10, 5 or 0 dB SNR. Neurograms were generated with the Zilany et al. auditory model under three neural conditions: normal innervation, high-SR only, and severe neural loss. A-C: NN1 results for the three conditions. D-F: NN2 results from the same conditions. Y-axes show true word labels; X-axes show predicted labels. Accuracy is indicated by concentration of values along the diagonal; overall percent correct appears below each matrix.
