Performance of noise training with different σ SNR . (a) White noise. (b) Cafeteria noise. White and cafeteria noises are injected, and μ SNR=15 dB. For each plot, the test data are corrupted by a particular ‘known’ noise. The ‘baseline’ curves present the results of the system trained with clean speech data, as have been presented in Table 1.
