Figure 8

(Color online) AIgrams at (a) 12 [dB] and (c) 6 [dB] SNR and (b) CPs for the feature-removed (–∞ [dB]) version of m118ka. As the SNR is decreased from 12 [dB], the recognition scores of the feature-removed sound unexpectedly increase. As an example, the scores of the feature-removed version of m118ka (d) at 6 [dB] SNR are greater than at 12 [dB] SNR. With only a few exceptions, the consonant score increases as the noise is increased from 12 to 6 [dB] SNR. Each of the four consonants is coded with a different symbol.
