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.

Several improvements have been made since the original ReSpeaker Mic Array v1.0. The first thing you may notice is the reduction of microphones. With the improved performance of the XMOS XVF-3000, including the improved full duplex AEC, we’ve been able to deliver increased performance with fewer microphones, and thus a lower cost.

  • Far-field voice capture enables you to capture and understand requests from up to 5m away
  • Acoustic Source Localization allows the device to know the direction of a sound source
  • Beamforming allows the device to focus only on sounds that come from the target direction 
  • Ignore background chatter through Noise Suppresion
  • Reduced environmental voice echo with de-reverberation
  • Removes current audio output with Acoustic Echo Cancellation
  • Compatible with most modern Linux, MacOS and Windows systems
