摘　　要：利用语音命令实现与智能设备的交互已经成为现代控制理论研究的热门话题之一。介绍了一种基于数字信号处理器(DSP)、语音采集模块、无线收发模块、片上外设等资源实现的语音命令控制处理系统。该系统首先通过语音采集模块采集到语音控制信号;然后通过DSP和相应的片上外设实现对语音命令的识别;最后将识别的语音命令传递给无线收发模块以实现对于智能设备的控制。整个系统的设计应用领域广泛,可以为人机交互提供一种切实可行的参考方案。Using voice commands to realize the interaction with intelligent equipment has become one of the hot topics in modern control theory. The voice command control processing system based on DSP, voice acquisition module, wireless transceiver module, on-chip peripheral resources is designed and realized. The voice control signals is acquired by the voice acquisition module in the system, and voice commands is recognized by DSP and on-chip peripheral resources, and the identified voice commands is transfered to the wireless transceiver module to control the intelligent equipment. The design application field of the whole system is very wide, and provides a kind of feasible and practical reference for human-computer interaction.
