VOICE PREDICTIVE ENCODER USING GUIDELINES FOR SELECTION OF CODING SCHEMES TO REDUCE THE SENSITIVITY OF FRAME ERRORS.

摘要

A method for encoding speech frames, comprising the steps of: encoding a predefined number of successive speech frames with a predictive coding mode (604); encode at least one voice frame with a less predictive coding mode (610), after carrying out the step of encoding a predefined number of successive voice frames with a predictive coding mode, the least predictive coding mode being lower predictivity than predictive coding mode; and repeat the two coding steps in order to generate a plurality of speech frames encoded according to a pattern.
