Gravity: Offline Language Learning Voice Recognition Sensor for Arduino / Raspberry Pi / Python / ESP32 - I2C & UART

FEATURES

• Self-learning function: Control the module to learn command words by the voice, and any audio can be trained as a command

• Support I2C and UART, with a Gravity interface

• Compatible with 3.3V/5V

• Built-in with 121 commonly-used fixed command words

• The module has a built-in speaker and an interface for an external speaker, which can provide real-time voice feedback on recognition results

• Equipped with power indicator (red) and recognition status indicator (blue)

• Dual microphones provide better noise resistance and longer recognition distance

• Compatible with Arduino controllers: Arduino UNO, Arduino Leonardo, Arduino MEGA, FireBeetle series controllers, Raspberry Pi, ESP32
