Voice Recognition Module V3 Compatible with for Arduino

The Voice Recognition Module is a powerful, easy-to-integrate solution for adding voice command functionality to your projects. It supports offline voice command recognition, meaning it does not require an internet connection to operate, making it ideal for standalone or embedded systems.

The module can typically be trained with up to 15 custom voice commands, which can be stored in groups or individually depending on the version. Once trained, it listens for specific keywords and triggers corresponding outputs or functions. The onboard microcontroller processes the voice inputs in real-time with high accuracy and minimal latency.

It communicates via UART (serial interface), making it compatible with most microcontrollers like Arduino, Raspberry Pi, and ESP32. Some versions may include onboard microphones, while others require external mics for better voice capture in noisy environments.

What’s new?

We already have Voice Recognition module V2. It supports 15 commands in all and only 5 commands at the

same time.

On V2, voice commands are separated into 3 groups while you training it. And only one group (5

commands) could to be imported into Recognizer. It means only 5 voice commands are effective at the

same time.

On V3, voice commands are stored in one large group like a library. Any 7 voice commands in the library

could be imported into recognizer. It means 7 commands are effective at the same time.

Parameter:

• Voltage: 4.5-5.5V
• Current: <40mA
• Digital Interface: 5V TTL level for UART interface and GPIO
• Analog Interface: 3.5mm mono-channel microphone connector + microphone pin interface
• Size: 31mm x 50mm
• Recognition accuracy: 99% (under ideal environment)
