Abstract
This paper describes the principle and process of speech signal proces sing system working in PCI bus，which is the advanced PC BUS. We took the ADPCM as the speech compress arithmetic and applied it to 'C54x, the fixed point DSP p roducing by Texas Instruments Corp. We got very good result in the experiment an d noise is hardly detected in speech after compressing. The theory combining with facts in the speech signal processing system is successful, and it will have a g ood market prospect.关键词
