Circuit Diagram — Voice Recognition System

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

The voice module digitizes these signals so the processor can analyze them. Voice Recognition System Circuit Diagram

Most modern modules use a "wake word" (like "Hello Robot") to listen for commands. Usually included with the module, but some circuits

You typically enter a learning mode via software or a button on the module. You repeat the command word multiple times (usually 3) until the module confirms success. Usually included with the module

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.
