ABSTRACT:
A system including an adaptive code book and a fixed code book for code excited linear prediction coding of speech signals is provided. The invention includes an embedded adaptive code book in the fixed code book and the selection procedure for selecting excitation vector parameters. A code book update system updates the fixed code book with embedded adaptive code book based on the long term processing excitation vector parameters with previous synthesized excitation.
