Abstract

A histogram-equalization method has been developed which can restore amplitude-distorted speech. A histogram of the input signal is modeled. The distribution function of the modeled input signal is compared to a reference distribution function. The mismatch can be used to describe the distorting nonlinearity and its inverse as an amplitude map which corrects the distorted signal.
