System Circuit Diagram: Voice Recognition

The processor compares the incoming sound frequency and "feature vectors" against templates pre-recorded during a training phase .

LEDs, relays (for high-power appliances), or a buzzer to confirm commands. Voice Recognition System Circuit Diagram

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 The processor compares the incoming sound frequency and

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 Setup and Training You must use the corresponding

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!

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