Voice Recognition Module V3, Speech Control for Arduino (80 Commands)
Original price was: ₵660.00.₵570.00Current price is: ₵570.00.
The Voice Recognition Module V3 lets you control Arduino, ESP32 and other microcontroller projects with your voice. It stores up to 80 voice commands that you train yourself, works offline and talks to your board over a simple UART serial connection. A microphone is included. You can buy it in Ghana from Innovice Technologies with same-day delivery in Kumasi.

The Voice Recognition Module V3 is a compact speech recognition module that adds offline voice control to your electronics projects. You don’t need internet or a cloud service. Record your own commands, such as “lights on”, “forward” or “stop”. When you speak one of them, the module recognises it and sends the result to your Arduino or ESP32.
Because you train every command yourself, you can use any word or short phrase in any language, including English, Twi and Ga. That makes this voice control module a strong choice for students, hobbyists and engineers in Ghana.
Key Features of the Voice Recognition Module V3

How to Get Started
- Wire the module to your Arduino as shown above.
- Install the VoiceRecognitionV3 library in the Arduino IDE.
- Upload the training example and record your voice commands.
- Load up to 7 commands to make them active.
- Use the recognised command number in your code to control LEDs, relays or motors.
Tips for best accuracy: train in a quiet room, keep commands to 1–2 words, and speak the same way you did during training.
Applications
