Voice Recognition Module V3 — 80 Commands, UART, Speaker-Dependent, Arduino CompatibleVoice Recognition Module V3 80 Commands, UART, Speaker Dependent, Arduino Compatible The Voice Recognition Module V3 is a compact speaker dependent voice recognition board that stores up to 80 user trained voice commands in onboard flash memory. Commands are trained by speaking into the onboard microphone and stored as acoustic templates. When a trained command is spoken, the module outputs the command index via UART to the host microcontroller
