In order to recover the excitation energy quickly and keep the adaptive excitation contribution percentage in the entire excitation after bit-stream packet loss, the two excitation gains (G<SUB>p </SUB> 305 and G<SUB>c </SUB> 306 ) can be first transformed into the two other special parameters: one is the entire excitation energy and another is the energy ratio of the adaptive excitation contribution portion relative to the entire excitation energy. Then, the transformed parameters are quantized and sent to decoder. At the decoder side, the quantized parameters are transformed back to the original form of the gains (G<SUB>p </SUB> 305 and G<SUB>c </SUB> 306 ).
