      Description

      Meet ReSpeakerMA2.png

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


      Several improvements have been made since the original ReSpeaker Mic Array v1.0. The first thing you may notice is the reduction of microphones. With the improved performance of the XMOS XVF-3000, including the improved full duplex AEC, we’ve been able to deliver increased performance with fewer microphones, and thus a lower cost.


      We’ll be offering our customization services for this device in the future. Contact iot@seeed.cc to learn more.


      Key Features.png

      Detect Far Away.gif


      Pick Up Voices From Far Away

      • Far-field voice capture enables you to capture and understand requests from up to 5m away



      Focus On Your Voice.gif


      Focus On The Right Voice

      • DoA allows the device to know the direction of a source

      • BF allows the device to focus only on sounds that come from the target direction

      • Ignore background noise and chatter through NS



      Improve Voice Quality.gif


      Improved Voice Audio Quality

      • Reduces environmental voice echo with de-reverberation

      • Remove current audio output with AEC


      Voice Demo.png

      If you think this sounds good, great! But let us prove it. One of our engineers recorded himself speaking over music being played. Hear for yourself how it really sounds with our full-duplex AEC demo below. 


      This is the raw data captured from the environment. There is no editing on this channel. Our engineer played some music from the device and spoke at the same time.

      Channel 1 Audio:


      This is the music that the device was playing at the time. 

      Channel 5 Audio:


      This is the end result after processing. The music was almost completely removed resulting in a high quality voice input.

      Channel 0 Audio:

      What do I need to make an audio recorder? Just the mic array or do you need the core as well? What are their different functions? Thanks.

      Hi Andrew~ The mic array need a upper computer (such as Raspberry), it only can pick up audio. The core can work as a recorder, you can consider the core as the array + Raspberry. Regards

      So in your demos where it separated the audio from the background noise, was that done on the V2 array or was that done on a separate computer? I need clean processed audio to come out of that jack on the array, is that what it does?

      Oh also is it possible to unsolder the mics so I can move them into other locations? Say within 5-10ft? Thanks!

      Hi,Andrew- the method of noise reduction was intergrated in the board, which included circut and algrithom, thanks!

      Thanked your reply:) The truth is, I didn't plug the speaker into the 3.5mm Headphone jack of the mic array,but into the mainboard of my intelligent speaker box. Is that the problem?I'm also confused that when I tested according to the AEC example, the audio of channel 0 was not good and there was still a lot of music :(

      Hi there~ For the AEC, The Echo Cancellation Channel is output buy the 3.5mm headjack. So if you do not use the 3.5mm jack, the mic array can not get the echo channel, there for the channel 0 is not good. Regards

      Is the processing that is shown on here only available if you are using the ReSpeaker's audio output jack? Or will this same processing work if music is played on an external speaker?

      yes, in the demo, we used an external speaker to plug into the 3.5mm jack. And it works well.

      that is not what was asked..they asked: if the music is being played say on a Sonos in the room (so not connected to the respeaker at all) will it be the same processing as shown in the demo above wave file samples?Or does the respeaker HAVE to be the device the music is being played through??I am guessing as the 3.5mm Audio Jack is output only.. your answer is incorrect.. the array has to have the music being played through it, not externally to it to produce the above processed audio demoSo the real question is how good is the mic array v2 at filtering out background music/talking and focusing on the voice in the DoA of the wake word ?

      Hi there~ You can consider our ReSpeaker Pro Case. As long as you do not put the mic array 2.0 with respeaker core v1.0, the case can work with the ReSpeaker Mic Array v2.0.

      Hi, I want to buy a mic array for a smart mirror with vocal recog, with a RPI3, but I'm not sure what to choose between de ReSpeker Mic Array v2 (here) and the ReSpeaker 4-Mic Array for Raspberry Pi ; which is better (distant vocal recognition, music from other source, etc.) and what's the real difference ? Thanks !

      Hi,there,Respeaker 4-mic arry is better one. Unlike respeaker 2-micspi HAT, this extension board is based on AC108, a developed, highly integrated four-channel ADC, I2S, and TDM hd voice input/output conversion.In addition, the 4-mics version provides a super cool LED with 12 programmable apa102 leds.With these four microphones and LED rings, Raspberry Pi will be able to perform VAD (voice activity detection), evaluate DOA (arrival direction), and display direction through LED rings, such as Amazon Echo or Google home.

      "The ReSpeaker Mic Array v2.0 has two firmware versions available, one including speech algorithms and a second for raw voice data" how can I know which version is in my hardware?
      on Jun 05,2018
      Replyupvote ()
      Hi there~ The factory firmware is six channels, if you have not burn the 1 channel version, then it should be the six channels. You can see more detail in our wiki. ### http://wiki.seeedstudio.com/ReSpeaker_Mic_Array_v2.0/#update-firmware ###. Moreover, in case you want to check it yourself. You can use the command ''sudo apt-install audacity'' to download audacity and use it to record the voice. you can pick six channel if you are using six channels version. More abouit audacity please read Q3 here. ### http://wiki.seeedstudio.com/ReSpeaker_Core_v2.0/#faqs ###
