Speech Coding Using Code Excited Linear Prediction

WebMay 15, 1998 · Abstract: We propose an adaptive encoding method of fixed codebook in CELP coders and implement an adaptive fixed code excited linear prediction (AF-CELP) speech coder. The AF-CELP exploits the fact that the fixed codebook contribution to the speech signal is also periodic as the adaptive codebook (or pitch filter) contribution. WebA speech coder based on a single-pulse excitation code-excited linear predictive coding (SPE-CELP) model of linear-predictive coding (LPC) is proposed and it is concluded that the coder produces significantly better speech quality than LPC10E, though the synthesized speech still sounds slightly buzzy for certain speakers. 13 man me hai vishwas book pdf free download
