By harnessing iFLYTEK's far-field noise reduction technology, the microphone array achieves a pick-up range of 10 meters, surpassing the performance of the 1st generation ring microphone array.

Utilizing microphone array technology, it achieves 360° speech signal collection. Through the TDOA algorithm (Time Difference of Arrival), it calculates the angle between the sound source and the module, accurately determining the speaker's direction. It can provide the azimuth angle and resolution of the sound source, up to 1°.

Utilize the iFLYTEK offline voice recognition engine for offline voice recognition capabilities.

The microphone array can be integrated with iFLYTEK voice cloud service for features like pronunciation correction and voiceprint recognition. (Registration is required.)

The module primarily supports Linux systems, with additional compatibility for Android. For customers lacking a Linux environment but requiring development of related technologies, we offer a pre-configured Linux virtual machine image specifically designed for Windows. This image can be easily downloaded and installed for immediate use.

The audio output of the ring 6-microphone array is compatible with the universal UAC protocol, allowing for plug-and-play functionality. The computer system can access the audio without requiring any special driver adaptation.

The wake-up status, along with the wake-up angle and other relevant information, can be retrieved through the serial port.

The microphone array includes development tutorials and ROS source code for PC, Raspberry Pi, and Jetson Nano platforms. It is compatible with a variety of controllers, meeting diverse development needs of users.
