语音识别无线开关控制装置的设计

摘要

In order to realize the operation of the wireless control device based on speech recognition technology,a device for controlling the on/off unit (such as an incandescent lamp) was designed.The chip LD3320 is used in the device as the data acquisition and processing module,the single chip microcomputer STC12C5A60S2 as the microcontroller of voice sampling comparison module,and the single chip microcomputer SCM STC15F104E as receiving and controlling microcontroller.The wireless communication module HC-12 is adopted to realize data signal transmission and reception.The device shows its perfect performances in speech recognition and wireless transmission.Its recognition rate is about 97％.The switch action of voice control lamp was realized by the device in the experiment.%为了利用语音识别技术来操控无线控制设备的运转,设计一种用语音无线控制开、关设备(白炽灯等)的装置.该装置利用LD3320作为语音数据采集和处理芯片,STC12C5A60S2单片机作为语音采样对比模块的微控制器,STC15F104E单片机作为接收、控制微控制器,利用无线通信模块HC-12实现数据信号发射和接收.结果表明,该装置在语音识别和无线传输上表现出良好的性能,识别率达到97％左右,且实现了语音控制灯的开关动作.
