In this paper the problem of recogmtlOn in noisy environments is addressed. Often, a recognition system is used in a noisy environment and there is no possibility of training it witJ� noisy samples. Classical speech analysis techniques are based on second-order statistics and their performance dramatically decreases when noise is present in the signal under analysis. In this paper new methods
