      Description

      ReSpeaker 4-Mic Array for Raspberry Pi is a quad-microphone expansion board for Raspberry Pi designed for AI and voice applications. This means that you can build a more powerful and flexible voice product that integrates Amazon Alexa Voice Service, Google Assistant, and so on.


      Different from ReSpeaker 2-Mics Pi HAT, this board is developed based on AC108, a highly integrated quad-channel ADC with I2S/TDM output transition for high definition voice capture. Besides, this 4-Mics version provides a super cool LED ring, which contains 12 APA102 programmable LEDs. With that 4 microphones and the LED ring, Raspberry Pi would have ability to do VAD(Voice Activity Detection), estimate DOA(Direction of Arrival) and show the direction via LED ring, just like Amazon Echo or Google Home.


      Note

      • Please note that the package does not contain Raspberry Pi.

      • Please note that there are no any audio output interfaces on ReSpeaker 4-Mic Array for Raspberry Pi. It is only for voice capture. And you could use the headphone jack on Raspberry Pi for audio output.


      Here is a video from Parvinder Yadav, it teaches how to use ReSpeaker 4-Mic Array for Raspberry Pi  to make google assistant. We really appreciate Parvinder's contribution to the community and hope this video can be a good help for you.

      That's really cool! It could potentially answer some of our need to have good mic in our conference room (and some project related to "limitation of the time to speak" and location of a speaker).Have you developed all the necessary drivers?Do you ship to Switzerland?
