Adaptive coding and optimal speech storage in digital speech interpolation systems
Pooja Tiwari, K.C. Harit · 2005
One of the important issue in speech interpolation is that of speech freeze-out which becomes a very serious consideration with multihop networks. The paper discusses the implementation of two such techniques namely speech storage and variable bitrate strategies with their independent and combined effects on the performance of multihop, DSI networks. The trade-off between the effective increased channel capacity and the degradation of the speech quality has also been pointed out. The basic architectural configuration of the system using multimicroprocessor system has been discussed and the potentialities of the method in accomodating newer versions of coding algorithms at desired speed of response have been included.
