Abstract
This article presents an overview of various nonlinear processing techniques applied to speech signals. Evidence relating to the existence of nonlinearities in speech is presented, and the main differences between linear and nonlinear analysis are summarized. A brief review is given of the important nonlinear speech processing techniques reported to date, and their applications to speech coding, speech synthesis, speech and speaker recognition, voice analysis and enhancement, and analyses and simulation of dysphonic voices.
