基于DSP语音识别系统的设计

Design based on speech recognition system of DSP

文章以TMS320VC5410DSP为中心设计一套语音识别系统,该系统主要通过对语音信号的处理完成对灾后生命体识别的效果,该系统主要由A/D和D/A转换TLC320AD50芯片完成语音信号的模数和数模转换,DSP芯片TMS320VC5410DSP完成语音信号处理和识别,及DSP外围电路,主要包括电源电路及存储设备等辅助电路的设计,本系统采用软硬件结合的方法以DSP为核心完成。

This article designed a speech recognition system based on TMS320VC5410DSP, this system completed post-disaster life recognition through processing of the speech signal , the system complete conversion of modulus and digifax by A/D and D/A TLC320ADS0, DSP chip TMS320VC5410DSP could complete speech signal processing and recognition, and DSP peripheral circuit, mainly including power circuit and storage equipment and other auxiliary circuit design, this system adopt the combining of software and hardware with DSP as the core.
