New Features Using Robust MVDR Spectrum of Filtered Autocorrelation Sequence for Robust Speech Recognition
Figure 7
Recognition accuracies for different features in various noise types of test set B of Aurora 2 task. RAS and PMCC refer to RAS-MFCC and perceptual MVDR-based cepstral coefficients, respectively. PMSR and R-PMSR are the proposed robust features.
