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