It can be further developed with detailed development tutorials and application routines, such as Text to Speech (TTS), directional meeting recording, real-time translation, and voice-controlled robots. Additionally, it can be integrated with iFLYTEK voice cloud service for features like pronunciation correction and voiceprint recognition. This versatile module finds applications in various fields, including voice-controlled smart homes, meeting recording, real-time translation, robot voice interaction, pronunciation correction, and intelligent vehicle cockpits. Version Introduction The latest version of the iFLYTEK ring microphone array features an enhanced split design, separating the microphone array from the module mainboard. This allows users to easily add other linear microphone arrays to the module mainboard. Additionally, this design extends the module's pickup range to 10 meters. Provide Protective Casing An optional protective casing enhances the appearance of the robot when you attach the microphone array. Expansive 10-Meter Pick-Up Range 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. 360° Sound Source Localization 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°. Offline Voice Recognition Utilize the iFLYTEK offline voice recognition engine for offline voice recognition capabilities. Support iFLYTEK Voice Cloud Service The microphone array can be integrated with iFLYTEK voice cloud service for features like pronunciation correction and voiceprint recognition. (Registration is required.) Support Text to Speech (TTS) Echo Cancellation Voice Wake Up Noise-Reduced Audio Provide Configured Development Environment 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. Universal UAC Protocol 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. Support Serial Port Communication The wake-up status, along with the wake-up angle and other relevant information, can be retrieved through the serial port. Support PC/ Raspberry Pi/ Jetson Nano 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.
