(English Abstract)
This paper proposed an improved 4.8kbps VSELP in order to keep the good quality in band-limited channel. In the most cases, it is difficult to keep the good quality at the low bit rate. In order to solve the problems, many methods are proposed, but they are not suitable to the Korean language structure because they are designed for being suitable to the foreign language structure. In experiment, we use the noseless Korean voice data. We show that the proposed 4.8kbps VSELP is not excellent to the 8kbps VSELP in SEGWSNR(Segmentally Weighted SNR), but it is the superior to the 8kbps VSELP in the MOS(Mean Opinion Score) test.
