A Low Bit Rate Speech Coding Method Based on CELP and LZH
I Dep · Communications technology · 2000
This paper presents a hybrid coder based on LD - CELP and LZH. The hybrid coder successfully compressed the 64 kbps telephone quality speech signal to 9.6kbps without introducing new delays. Moreover, the reconstructed speech singal has maintained the high perceptual quality and readbility.
