Voice Recognition Module V3

Talk to Your Tech

The Voice Recognition Module V3 is designed to recognize and process predefined voice commands. Unlike smart speakers that rely on the cloud, this board processes audio locally (offline), ensuring instant response times and total privacy. You can train it to recognize specific words (like “Lights On,” “Move Forward,” or “Open”) and trigger actions immediately.

High Precision & Flexibility

Equipped with a high-quality microphone, this module boasts a recognition accuracy of up to 99% in ideal environments. It communicates via a standard 5V TTL UART interface (RX/TX), making it compatible with almost any microcontroller, including Arduino UNO, Mega, Leonardo, and Raspberry Pi.

Versatile Applications

Whether you are building a voice-controlled wheelchair, a smart light switch, or a conversational robot, this module handles the heavy lifting. It supports a 3.5mm mono-channel microphone (included) for flexible placement.
