NRK2202-A01 module is an intelligent MCU module specialized in the field of IoT interaction and control. Based on the most advanced deep neural network (DNN-HMM) speech recognition technology, this intelligent module realizes high recognition rate, high real-time, local and cloud combination, highly integrated speech recognition and processing functions; it can realize specific intelligent speech interaction effects such as semantic recognition. At the same time, the module has the control and calculation processing capability of a conventional MCU, and can realize various applications that require communication and control. The module supports far-field voice pickup, noise suppression, offline voice wake-up, echo cancellation, local command word self-learning, voiceprint recognition, WIFI network control and OTA upgrade.
The NRK2202 is an offline voice-recognition interaction + infrared solution that allows users to turn their home air conditioners, fans, and lighting into intelligent devices in seconds. This offline voice recognition solution does not require internet connection or APP download for voice control of home appliances. It can be fully applied to small and large smart home appliance devices, such as fans, air conditioners, smokers, table lamps, drying racks and switch panels, etc. The NRK2202 module has a low-power consumption, effective recognition rate of more than 95%, recognition distance of more than 5 meters, and more than 80 words with many advantages.
