Offline voice robot

This project is based on a low-cost offline speech recognition module SU-03T produced by Movement Intelligence Company. It realizes the three functions of offline voice dialogue, expression display, and turning on and off the desk lamp. It is mainly used to introduce children to programming and practice programming. thinking.

SU-03T supports customer-customized voice dialogue question and answer content, including custom wake words, uploading custom audio and other functions, and the price/performance ratio is amazing. After programming and uploading through the website http://www.smartpi.cn/#/ , the serial port can be downloaded to the module.

In addition, this project uses STC microcontroller and TM1629 to drive the LED array to display expressions, which increases the cuteness of the robot and attracts the love of children. For this product's LED array expression model, I used VS2017 to create a small software zimuVS.exe.

Note when purchasing components:

1. The use of high-sensitivity microphones is better. This project uses Xinfeng Electronics' "high-sensitivity microphone 26DB 6050P with needle plug-in electret"

2. Purchase a normally closed type of desk lamp relay so that it can light up when plugged in without having to send voice commands every time it is plugged in.
