Abstract
The method of speech coding CELP is extensively used in much voice communication-, multimedia-, video conference and other systems. There are a lot of papers related to CELP coding characteristics improvement for a better speech quality after decoding. Most of the papers are dedicated to lower the rate of CELP coded speech transmission. One problem related to low rate CELP speech transmission with a good speech decoding quality is noising in the channel for transmission. The goal of this paper is to combine the advantages and the possibilities of CELP speech coding to reduce the rate of transmission and the methods of channel coding to protect the most important CELP coding parameters in each speech frame such as line prediction coefficients, excitation indexes etc.
