ARMA model based speech coding at 8kb/s

Research output: Contribution to journal › Conference article › peer-review

Abstract

A novel speech coding approach is proposed that gives high-quality performance at 8 kb/s. The coder is based on an autoregressive moving-average (ARMA) model as the prediction filter and a new excitation model. A simple ARMA analysis method is proposed that features a technique for eliminating the fine harmonic structure within the speech spectrum. This overcomes the problem of MA parameter misestimation. The excitation signal is modeled as a pulse train whose density is varied depending on the residual signal's power. The proposed coder produced high-quality speech comparable with 6-b log PCM at 8 kb/s according to computer simulation.
