DSP technology in audio processing is applied more and more widely field. At present in many speech processing systems are used in speech analysis module, spectrum analysis is carried out to collect sound and. High speed TMS320C5416DSP chip by the design of the system, the highest frequency can reach 160MIPS, can solve good system;the digital coding and decoding with 16~32 sampling accuracy of the chip TLV320AIC23, combined with the audio codec chip and TMS320C5416DSP is a mobile digital audio system, the speech analysis system is the ideal solution for. First, given the overall design and working diagram, and then gives the hardware system design and software design of voice recording system based on TMS320C5416DSP chip. Finally, the availability and practicability of the system is verified by simulation.
