Seeed Studio ReSpeaker Mic Array Audio and Voice Board

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 AECTechnical Specifications● XVF-3000 from XMOS ● 4 High Performance Digital Microphones ● Supports Far-field Voice Capture ● Speech Algorithms On-Chip ● 12 Programmable RGB LED Indicators ● Microphones: ST MP34DT01TR-M ● Sensitivity: -26 dBFS (Omnidirectional) ● Acoustic Overload Point: 120 dBSPL ● SNR: 63 dB ● Power Supply: 5V DC from Micro USB or Expansion Header ● 3.5mm Audio Jack Output Socket ● Dimensions: 70mm (Diameter)Potential Applications● USB Voice Capture ● Smart Speaker ● Intelligent Voice Assistant Systems ● Voice Recorders ● Voice Conferencing System ● Voice Interacting Robot ● Car Voice AssistantCompatibility● Linux* ● macOS ● Windows *Linux recommended for firmware updates.Forums & Technical Information ReSpeaker Technical Support forum https://forum.seeedstudio.com/viewforum.php?f=87&sid=59eb85400233fef1d200136d58c3085f GitHub Wiki http://wiki.seeedstudio.com/ReSpeaker_Mic_Array_v2.0/
