The New version is available now, please ckick The ReSpeaker Mic array v2.0 to check.
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
Acoustic Echo Cancellation
XMOS microcontroller with 16 cores inside
7 high performance digital microphones
Supports Far-field Voice Capture (up to 10m)
Supports Beamforming, Acoustic Source Localization, Nosie Suppression, De-reverberation and Acoustic Echo Cancellation
12 programmable RGB LED indicators
Microphones: ST MP34DT01-M
Sensitivity: -26 dBFS (Omnidirectional)
Acoustic overload point: 120 dBSPL
SNR: 61 dB
Power Supply: 5V DC from Micro USB or expansion header
Dimensions: 70mm (Diameter)
Here is a video from Parvinder Yadav, it teaches how to use ReSpeaker Mic Array - Far-field w/ 7 PDM Microphones to make google assistant. We really appreciate Parvinder's contribution to the community and hope this video can be a good help for you.
With ReSpeaker Mic Array, now we can build Google Assistant on Raspberry Pi!
ReSpeaker responds to your voice and recognize your speeches based on powerful online cognitive services like Microsoft Cognitive Service, Amazon Alexa Voice Service, Google Speech API, Wit.ai and Houndify.
With ReSpeaker Mic Array, now we can build Google Assistant on Raspberry Pi !!!Hotword detection, cool LEDs and easy installation, it is worthy for you to make one for yourself. Own your own Artificial intelligence assistant from now on:)
ReSpeaker Mic Array, as the “ear” of Raspberry Pi here, can listen to your speech commands and send them to Raspberry Pi. According to your commands, Raspberry Pi will control Wio Link to do what you want via Wi-Fi. We have talked the smart home for so ma

Wiki of ReSpeaker Mic Array - Far-field w/ 7 PDM Microphones
<p>Hi the minimum angle is 60°。For more information please check in on our wiki page.</p><p>http://wiki.seeed.cc/Respeaker_Mic_Array/<br></p>
Hi~Since all the mic is upwards,we suggest you put the MIC array on the top of your box,and please make sure you have enough hole to let the sounds in.Thanks
Hi Alex~ We have not tried a near-field application, but I think it is an awesome idea, maybe you can have a try.
But I must admit that, we can not offer much hlep for you with this. Regards
Hi there~ Sorry to tell you that, we do not have the driver for Windows 10 lot.
Sure you can. We suggest you use Audacity to recorde the voice on windows.
Hi Michael~ The detect distance of ReSpeaker Mic Array is within 4 meters.So I'm afraid that 20feet is out of range.Regards
Hi there~ Unfortunately Windows 10 LoT for Raspberry Pi do not support Respeaker Mic Array.
Hi there~ 0x83 version do support noise suppression, it just output the original voice.You need to use the 0x32 firmware.Regards
Hi there~ please refer the comment below.regards
Hi there~ Please use ubuntu to update the firmware follow the guide here ### https://github.com/respeaker/mic_array_dfu ### Or you can use Mac follow the guide here ### https://github.com/jerryyip/respeaker_micarray_dfu_mac_linux ### In case you still have problem,please email us ### firstname.lastname@example.org ### Regards.
Hi there~ There will be an upgrade version of ReSpeaker Mic Array available soon.Let's say march, and the ReSpeaker Mic Array will be much more better when it comes back.Definitelly, worth waiting.
Same problem. Did you find a solution? Or did they reply?
Yes, we need PC/raspberry/mac to extract the DOA. for more source localization, please refer to https://github.com/introlab/odas thanks.
Hi there~ Yes, it can work as a normal microphone.Regards
Hi there~ I'm afraid this one will not.Fortunately,the 2.0 version is one the way.And the 2.0 version is much better.Stay tuned.Regards
Hi there~ Beacause the DSP chip Xmos2000 is discontinued.Fortunately,we will use Xmos3000 instead.Besides we‘ve upgraded for both hardware and software,the new version will be much better.Stay tuned.Regards
Hi there~ This one will not be back.But the 2.0 version will be available as early as March.The V2 is much better.Thanks for your concern,stay tuned.Regards
Hi there~The new version will be available as early as March.Stay tuned.Regards
Hi there, we have 7 mic raw data and 1 channel average data. that's why 8 channels. there are 2 firmwares, one is raw for 8 channels and the other is 2 channels data with dsp support. thanks.
