A design of 0.9kb/s speech coding algorithm based on MELPe

Abstract

A 0.9kb/s speech coder based on the 2.4kb/s Enhanced Mixed Excitation Liner Prediction (MELPe) analysis algorithm is presented in this paper. At the part of speech coding, the feature parameters of three consecutive frames are extracted using the same algorithm as in the 2.4kb/s MELPe standard and then grouped into a super-frame, new quantization schemes… (More)
