Step into the realm of hands-free automation. The Voice Recognition Module V3 is a compact, high-performance board that brings offline speech recognition directly to your microcontrollers. Unlike cloud-dependent smart speakers, this module processes audio entirely on the edge. This guarantees near-zero latency and total privacy for your voice-activated robotics, without ever needing a Wi-Fi connection.

As an IIT Bhubaneswar-incubated tech ecosystem, XROBOTICS WORKS recognizes that natural human-machine interaction is the future of engineering. This module is speaker-dependent, meaning it is specifically trained to recognize the unique vocal nuances of the operator. You can record up to 80 distinct commands (such as “forward,” “stop,” or “lights on”), with up to 7 commands active simultaneously in the listening buffer. Communicating effortlessly with your Arduino, Mega, or ESP32 via standard UART (Serial), it is the core component behind advanced B.Tech projects like voice-controlled robotic arms and automated accessibility wheelchairs deployed in PM Shri Labs.
