      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?

      Hi, my raspberry pi 3 B+ has some problem with detecting respeaker 4 hat microphone as default microphone. Sometimes the microphone works and can record with good quality, but sometimes it looks like the raspberry pi didn't found the microphone especially after a reboot. Is it a known bug of raspberry pi 3 B+? I installed all the drivers properly like in the instruction, otherwise the microphone should not work at all. Thank you in advance.

      Hi there~ Yes you can, you can change the default 0° at the **python kws_doa.py** file. Have fun.

      Just to know the energy consumption of the ReSpeaker. On my project I'm using several devices on the RPi. I want to choose the best power supplie, that provides enought current.
