Product Details

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 on-board hardware-enabled algorithms are powered by the XMOS XVF-3000.

Several improvements have been made since the original ReSpeaker Mic Array v1.0. With the improved performance of the XMOS XVF-3000, including the improved full duplex AEC, version 2 delivers increased performance with fewer microphones, and at a lower cost.

Key Features

● Detect voices from up to 5m away
● Beamforming allows the device to focus only on sounds that come from the target direction
● Direction of Arrival (DoA) enables the device to know the direction of a source
● Background noise and chatter is ignored through noise suppression
● Environmental voice echo reduced with de-reverberation
● Audio output removed using AEC
