Online Voice recognition modules require a reliable internet connection to generate responses and are not independent of the Microcontroller/Processor controlling them. While one can create an offline voice recognition module using a compatible processor like RaspberryPi, and train a custom neural network to do this, it is not feasible for battery-operated edge devices

This Grove-Offline Voice Recognition Module is a truly offline voice recognition module with 150 pre-programmed voice commands, which can be communicated through UART. It features connections for the speaker and microphone, along with indicator LEDs. The power supply to the module is ESD-protected, adding more safety to the module. It is a perfect low-cost solution for adding voice control to your IoT projects!
