Speaker microphone

The ReSpeaker Mic Array v2.0 is a hardware-based solution for creating or supplementing voice interfaces for your projects. The board is a long-range microphone array device that is able to record voices up to a distance of 5 m even in the presence of background noise. The hardware-based onboard algorithms are supported by the XMOS XVF-3000.

Several improvements have been made since the original ReSpeaker Mic Array v1.0. The first thing you might notice was the reduction of the microphones. With the improved performance of the XMOS XVF-3000, including the improved full-duplex AEC, we were able to achieve higher performance with fewer microphones and thus lower costs.
