| Abstract: | This paper introduces an approach with low rate speech coding technology(ITU T G.729A) to design low rate speech communication devices based on AC4880xC C vocoder.The theory and practice show that this system has advantages of lower coding rate,higher quality of synthetic voice,better ability to reduce the bit error rate,and can efficiently improve the utility ratio of bandwidth.It is of great value in practical application. |
