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.
Usually included with the module, but some circuits use an external earpiece or computer microphone. Voice Recognition System Circuit Diagram
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. Building a voice recognition system circuit is usually
The voice module digitizes these signals so the processor can analyze them. Voice Recognition System Circuit Diagram
The processor compares the incoming sound frequency and "feature vectors" against templates pre-recorded during a training phase .
