Journal ArticleDOI
Fast Recovery for a CELP-Like Speech Codec After a Frame Erasure
TL;DR: A technique to improve the recovery after a frame erasure is proposed in a constrained excitation search at the encoder and a resynchronization procedure at the decoder that does not need additional delay.
Proceedings ArticleDOI
Resynchronization of the Adaptive Codebook in a Constrained celp Codec After a Frame Erasure
TL;DR: The method consists in adequately shifting the last pitch pulse present within the corrupted adaptive codebook memory so that it is resynchronized with the excitation parameters of the frame that follows the erased one.
Proceedings ArticleDOI
Increasing the robustness of CELP-based coders by constrained optimization
TL;DR: It is shown that a constrained search of the adaptive and innovative codebooks significantly improves the recovery time of the decoder after a lost frame, at the cost of only minor quality degradation in a clear channel.
