Offline smart voice box for smart home

Project Description:
Turning lights on and off, turning on the TV and air conditioner are the most common operations in daily life. This project aims to simplify this process. Don't want to get up to turn off the switch if it's far from the bed? Just tell Xiao Hei (a smart speaker). Xiao Hei will turn it off. There are many smart speakers available now, but why not buy a ready-made one? Because they all need to be connected to the internet. If their service or network is down, you're helpless. Therefore, a local offline solution is crucial.

Design Principle
: ASRPro implements offline voice recognition, transmitting the data via serial port to the ESP8266. The ESP8266 then forwards the commands to Home Assistant or an MQTT server.
Software instructions
are attached.
Physical demonstration
and design notes:
ASRPro's serial port uses a 5V pull-up resistor.
