Error concealment using residual redundancy for MELP parameters
Soft bit speech decoding. as a new approach of error concealment. is applied to the mixed excitation linear prediction (MELP) algorithm. Average residual redundancies of the quantized parameters are exploited in the error concealment process as an a priori knowledge of the source. Results show a significant SNR improvement for parameters decoded using the error concealment scheme.
