Abstract
Low-delay techniques are proposed for coding 7 kHz speech using subban d code-excited linear predictive coding (CELP). The use of separate an d joint index codebooks is compared. Specifically, the joint-index-sub band CELP (JISBC) algorithm is found to provide good quality with proc essing delay in the range 2.375-3.375 ms at corresponding bit rates of 16-8 k bit/s.
