Design of smart voice interactive home system based on NodeMCU

In view of the fact that traditional home appliances are difficult to directly integrate with voice assistants on the market,the price of high-tech products is difficult to benefit the people,and smart home control systems are difficult to achieve popularization due to high design costs,this article proposes Raspberry Pi is used to develop a high cost-performance smart voice interactive home system jointed with NodeMCU development board.The design uses the Raspberry Pi 4 B+to run the SDK provided by the Baidu cloud platform under the Linux system,plus the microphone array and CSI camera to realize functions such as speech recognition,speech synthesis and face recognition.The Python serial library is used to communicate with the Arduino serial port,and the Raspberry Pi sends the voice-recognized instructions to the Arduino to realize the voice interaction between humans and hardware devices.NodeMCU uses the built-in ESP8266 chip to compile with Arduino IDE to connect the data collected by the sensor to the IoT cloud platform through the TCP protocol for realizing remote storage of data,remote observation and remote control of home environment information.The operation results show that wireless transmission of home environment data and the functional requirements of voice interaction are realized,the design cost is low,the function is powerful and the expansion is convenient.The system realizes multi-platform interaction and improves the multi-task parallel processing capability.
