Abstract

A median-rate speech delta coder with low complexity is presented in this paper. It combines the features of one-step look-ahead decision, syllabic companding, instantaneous companding, and adaptive prediction. This coder uses not only short-term prediction filter but also long-term prediction filter to estimate the current speech sample. The performance for this coder with and without pitch prediction is compared by computer simulation. Comparisons between the performance of this coder and the performance of CVSD are also included
