Gravity Offline Language Learning Voice Recognition Sensor for Microbit/Arduino / ESP32 - I2C & UART

The Gravity Offline Language Learning Voice Recognition Sensor offers a convenient solution for creating a custom voice assistant. By pairing it with the HiLetgo ESP32 Board, users can control their custom smart switches with ease. The documentation provided on the DFRobot website is comprehensive and offers all the necessary information for utilizing the device effectively. However, one drawback of the Gravity sensor is the lack of a listening mode that can be triggered via the connected microcontroller. There is only one built-in wake-up command and one user-programmable command. This limitation may be a hindrance for users who require more flexibility in their voice assistant setup. Furthermore, some customers have reported issues with the product's reliability. The device does not seem to retain custom commands or wake-up voice, rendering it impractical for long-term use. This has led some customers to Consider investing in a more reliable alternative. Overall, while the Gravity Offline Language Learning Voice Recognition Sensor provides a viable solution for offline language learning and voice recognition projects, its limitations and potential reliability issues should be taken into Consideration before purchase.
