Voice Recognition System Circuit Diagram «iOS PREMIUM»
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
The processor compares the incoming sound frequency and "feature vectors" against templates pre-recorded during a training phase . Most modern modules use a "wake word" (like
Usually included with the module, but some circuits use an external earpiece or computer microphone. relays (for high-power appliances)
Note: Pins 2 and 3 are often used with the SoftwareSerial library to keep the main hardware serial free for debugging. 3. How the System Works
LEDs, relays (for high-power appliances), or a buzzer to confirm commands.
