Abstract
This letter proposes an LSP quantizing method which uses interframe co rrelation of the parameters. The quantized parameters are represented as a moving average of code vectors. Using this method, LSP parameters are quantized efficiently and the degradation of decoded parameters c aused by bit errors affects only a few following frames.
