| Abstract: | A speech compression and decompression processing system based on TMS320VC549 16 bit fixed - point DSP chip is proposed in this paper, which is designed by using TLC320ADSOC A/D converter and D/A converter, and with 100MIPS processing capacity and 8kHz sample rate. The system is applicable for speech coding , recognition, synthesizing and so on. The experimental results show that the system is stable, flexible and universal for speech compression and decompression processing. |
