Title: Auditory speech preprocessors

Abstract

A nonlinear transmission line model of the cochlea (Zweig 1988) is proposed as the basis for a novel speech preprocessor. Sounds of different intensities, such as voiced and unvoiced speech, are preprocessed in radically different ways. The Q's of the preprocessor's nonlinear filters vary with input amplitude, higher Q's (longer integration times) corresponding to quieter sounds. Like the cochlea, the preprocessor acts as a ''subthreshold laser'' that traps and amplifies low level signals, thereby aiding in their detection and analysis. 17 refs.
