Abstract
A method and system for representing speech with greatly reduced harmonic and intermodulation distortion using a fixed interval scale, known as Tru-Scale. Speech is reproduced in accordance with a frequency matrix which reduces intermodulation interference and harmonic distortion (overtone collision). Enhanced speech quality and reduced noise results from increasing the signal-to-noise ratio in the processed speech signal. The method and system use an Auto-Regressive (AR) modeling technique, using, among other approaches, Linear Predictive Coding (LPC) analysis. In accordance with another aspect of the invention, a Fourier transform-based modeling technique also is used. The application of the system to speech coders also is contemplated.
