To build a basic voice-controlled circuit, you will need the following hardware: An Arduino Uno or Arduino Nano is typically used as the central brain. Voice Recognition Module: Common options include the Elechouse Voice Recognition Module V3 or the DFRobot Gravity Sensor Go to product viewer dialog for this item.
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 to confirm commands.
Most modern modules use a "wake word" (like "Hello Robot") to listen for commands.
Building a voice recognition system circuit is usually done in one of two ways: using a (like the Elechouse V3 Go to product viewer dialog for this item.
The microphone picks up analog sound waves and converts them into electrical signals.
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
