The ReSpeaker Mic Array v2.0 is a hardware-based solution for creating or adding voice-interface to your projects. The board is a far-field microphone array device capable of detecting voices up to 5m away even with the presence of background noise. The onboard hardware-enabled algorithms are powered by the XMOS XVF-3000. Including the improved full duplex AEC, Able to deliver increased performance with fewer microphones, and thus a lower cost.
Highlighted Features
- Pick up voices from far away far-field voice capture enables you to capture and understand requests from up to 5m away
- Improved voice audio quality by removing current audio output with AEC
- Reduces environmental voice echo with de-reverberation
- DoA allows the device to know the direction of a source
- BF allows the device to focus only on sounds that come from the target direction
- Ignore background noise and chatter through NS
- When it comes to development we believe you should have as many options as possible. The ReSpeaker Mic Array v2.0 is able to work with most modern Linux, macOS, and Windows systems*
