摘　　要：首先对语音识别技术的应用方向及数字信号处理器作了简要介绍,然后以TMS320VC5410型DSP芯片为核心构建了语音识别系统,并采用动态时间归整算法DTW作为识别算法。该系统在小词汇量的孤立词语音识别中获得了良好的识别性能。未来若对此识别系统作进一步完善后,再嵌入现代建筑或家居的电子类产品中,可很好地实现对这些电子类产品的智能化操作与控制,从而为人们带来更加方便、舒适的居住环境。Firstly, the application direction of speech recognition technology as well as digital signal processor were introduced briefly. And then, by taking TMS320VC5402 DSP chip as the core, a speech recognition system was constructed, which adopted dynamic time warping （DTW） as the recognition algorithm. The system had ob- tained a good performance under speech recognition of small vocabulary isolated words. Intelligent operation and control could be well achieved when the recognition system was embeded in electronic products of modem building or house after its function was improved in the future, which would bring people with more convenient and comfortable home environment.
