Voice Recognition System Circuit Diagram Direct

LEDs, relays (for high-power appliances), or a buzzer to confirm commands.

Most modern modules use a "wake word" (like "Hello Robot") to listen for commands.

Once a match is found, the module sends a specific Command ID (e.g., "1" for "Lights On") over the TX pin to the Arduino, which then triggers a relay or LED. 4. Setup and Training Voice Recognition System Circuit Diagram

Usually included with the module, but some circuits use an external earpiece or computer microphone.

You must use the corresponding library in the Arduino IDE to read the recognized IDs and perform tasks. How to Use Voice Recognition Commands With Arduino! LEDs, relays (for high-power appliances), or a buzzer
