代码测试
注意，树莓派的串口出厂状态是绑定到蓝牙的，然后我们使用引导字符和一些调试接口，这里我们应该记得打开树莓派的正常串口通信功能，使用串口进行正常的数据通信。

Note that the raspberry pie serial port factory status is bound to Bluetooth, and then we use the boot character and some debugging interface, here we should remember to turn on the raspberry pie normal serial communication function, use the serial port for normal data communication.
连接语音模块和覆盆子馅饼并运行程序。

Connect the voice module and raspberry pie and run the program.
所有指令均可识别成功！
下一步，可以根据语音识别的不同指令操纵相应的继电器，从而实现对智能家居中不同灯光的语音控制，详细代码发布在博文中。

In the next step, the corresponding relays can be manipulated according to the different instructions of speech recognition, so as to realize the voice control of different lights in the intelligent home, and the detailed code is posted in the blog post.
