Description
Elechouse V3 Voice Recognition Module
This compact module provides voice recognition and control for Arduino-compatible projects. It can store up to 80 voice commands, with up to 7 active at once. Commands can be accessed through the serial port or the onboard GPIO pins.
The V3 board stores up to 80 voice commands, each up to 1,500 ms long, and compares input with the voice patterns previously recorded during training. Train the module before using it to recognize commands. The source states that commands can be recorded in any language, or as other sounds.
