NOTE:
This product was discontinued due to a supply chain issue - but don't worry! We will have a new and improved version before April 2018!
Update: April 8th, 2018 - We will be announcing the ReSpeaker Mic Array v2 soon. We expect to manufacture near the end of this month.
The ReSpeaker Mic Array can be stacked (connected) right onto the top of ReSpeaker Core to significantly improve the voice interaction experience. It is developed based on the XVSM-2000 Smart Microphone from XMOS. The board integrates 7 PDM microphones to help enhance ReSpeaker's acoustic DSP performance to a much higher level. With the Mic Array attached onto the top of the ReSpeaker Core, ReSpeaker is now able to:
Far-field Voice Capture
Acoustic Source Localization
Beamforming
Noise Suppression
De-reverberation
Acoustic Echo Cancellation
XMOS microcontroller with 16 cores inside
7 high performance digital microphones
Supports Far-field Voice Capture (up to 10m)
