The most common approach for DIY projects involves an Arduino Uno Go to product viewer dialog for this item. connected to a voice module via serial communication. 1. Essential Components Voice Recognition System Circuit Diagram
The circuit relies on a connection between the voice module and the microcontroller. Voice Module Pin Arduino Pin VCC Power supply (typical 3.3V-5V) GND Common ground RX Pin 3 (Digital) Receives data from Arduino TX Pin 2 (Digital) Transmits voice ID data to Arduino Usually included with the module, but some circuits
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. connected to a voice module via serial communication
A 5V regulated DC supply is standard for these components. 2. Circuit Diagram Connection Guide
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!
Most modern modules use a "wake word" (like "Hello Robot") to listen for commands.
