Upper and lower bounds on the mean of noisy speech application to minimax classification.

Upper and lower bounds on the mean of noisy speech application to minimax classification.

In this paper, we derive upper and lower bounds on the mean of speech corrupted by additive noise. The bounds are derived in the log spectral domain. Also approximate bounds on the first and second order time derivatives are developed. It is also shown how to transform these bounds to the mel freque...
