iFLYTEK Far-Field Microphone Array Module ROS Six-Microphone Voice Board 6-Microphone Sound Source Positioning Navigation
- Real-time Translation
- Sound Source Localization
- Support ROS
- TTS (Text to Speech)
- Offline Voice Recognition
- Echo Cancellation
- Audio Noise Reduction
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.
