“…In the first class of algorithms, spectral and wavelet-based speech enhancement techniques were studied in [1,2] and were proven to be noise and SNR level-dependent (performance can improve or degrade depending on the noise / SNR). NFM-based speech enhancement algorithms were also presented in [3][4][5] and showed relatively low improvement compared to other techniques (10% of relative improvement in EER. In the cepstral domain, several stochastic compensation techniques were applied in [6] (such as RATZ [7], SPLICE [8], TRAJMAP [9] and SSM [10]) and were proven to be highly efficient in noisy environments but such algorithms assume prior knowledge about the test noise.…”

“…Dealing with noise has also been one of the principal areas of interest and different techniques have been proposed to deal with it in different domains. In the temporal domain, speech enhancement techniques [11][12][13] have been proven to be noise and SNR-level dependent yielding low improvement rates (10% of relative EER improvement). In the cepstral domain, several stochastic compensation algorithms have been proposed in [14] and have been shown to be effective when prior knowledge about test noise is available.…”
