Statistical signal mapping: a general tool for speech signal processing
Y.M. Cheng, Douglas D. O’Shaughnessy, Paul G. Mermelstein · 2003
Various forms of speech processing in practice take, or can be transformed to, the same form of input/output, and the relation of input/output generally can be expressed by a nonlinear function. This paper proposes a framework for identifying statistically the non-linear function concerning the statistical nature of speech. It demonstrates the applicability of this framework in a particular context, that of speech recovery.>
