Description
The Voice Recognition Module is a compact speech recognition board designed for seamless integration with Arduino and other microcontrollers. It supports up to 80 user-trained voice commands, with a maximum of 7 active commands loaded at one time through its internal recognizer. Operating at 4.5–5.5V with UART and GPIO control, the module enables reliable speaker-dependent voice control. With onboard flash storage and 5V TTL interface, it is suitable for robotics, automation systems, and interactive embedded applications.
