Abstract

Abstract

A new auditory system model based on a combination of physiological andpsychological acoustic data has been proposed. This model consists of a bank of nonuniform bandpass filters, detectors and main-frequency choosing mechanisms, they act as basilar membranes, inner hair cells and nerve fibers, respectively. Combining with the improved critical bandwidth parameters, the input to this model is analogous to the pressure at the eardrum, and the output of this model simulates various features of the firing patterns. The synthesizer obtains the resultant speech by use of the simple adding method. Computer simulations show that the resultant speech is highly intelligible and natural. The proposed model is correct, and the improvement of the critical bandwidth parameters is effective.
