Title

Frequency-Space Contractive Speech Coding

Abstract

This paper describes a very efficient speech coding scheme with compression ratio of up to 120:1. The difference between the FIT of two consecutive frames of speech is considered to be a two dimensional image in the frequency domain. Using linear contractive transformation this image can be reduced to a set of rules and coefficient that could either be transmitted or stored. The speech signal is reconstructed using these coefficients with minimal loss of signal quality. The output speech is superior in quality to that of LPC speech. This algorithm can be applied equally to the one and two dimensional signals providing a possible solution for the hypermedia problem.
