越来越多的智能家居进入人们的生活，如何对智能家居进行简单有效的控制是一个难题。设计一个无线语音 控制系统，主要由语音识别模块、单片机、无线发射模块和无线接收模块组成。编程中，通过简单地设置芯片的寄存器，将“你 好”这样的关键词传入芯片中，芯片就可以识别“你好”。试验结果表明语音模块可以准确识别口令并通过无线发射模块发送 信号，实时控制电器的电源通断。本系统可以代替人工接触电源开关更方便地控制家中的电器。

More and more intelligent households enter into people's lives. How to control the smart home in a simple and effective way becomes a difficult problem. This paper designs a wireless voice control system, consisting of the speech recognition module, microcontroller, wireless transmitting module and the wireless receiving module. In the program, sending "hello" into the chip by simply setting the chip registers can identify "hello" by the chip. The experimental results show that the voice module can accurately identify the password and send signals through the wireless transmitting module, and control the electric power on and off in real time. The system can control home appliances more easily instead of the manual contact power switch
