| Abstract: | Digital signal processing (DSP) technology is one core technology of modern digital speech communication,and the applications of DSP technology have established the foundation for speech collecting,processing and broadcasting.In this paper,the design of speech signal processing system based on digital signal processor is proposed,and the hardware platform is constructed utilizing TMS320VC5416 processors and AIC23 voice chip.Based on the characteristic analysis of DSP and audio codec,the software control interfaces have been configured,and the digital audio data transmission are implemented.The applications main program and subprogram are designed by using the mixed language compilation with C and assembly (ASM) language.And then some functions have realized in this speech signal processing system in debugging,which are audio collection,signal recording and sending out,and digital echo. |
