Seeed Studio ReSpeaker 4-Mic Array for Raspberry Pi, Raspberry Pi Microphone #adseeed studio #ad
- Respeaker 4-mic array does not have audio output. 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, estimate doadirection of arrival and show the direction via led ring, which contains 12 apa102 programmable LEDs.
With that 4 microphones and the led ring, raspberry pi would have ability to do VADVoice Activity Detection, this 4-Mics version provides a super cool LED ring, just like Amazon Echo or Google Home.
Respeaker 4-mic array for raspberry pi（pi 3/pi 4 b + is a 4 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.
If this is a requirement please consider the respeaker 6-mic Circular Array Kit For Raspberry Pi, the ReSpeaker 4-Mic Linear Array Kit for Raspberry Pi, or the ReSpeaker Mic Array v2. 0 This raspberry pi microphone support all raspberry pi models, Raspberry Pi 1 B+, Pi 2 B, Pi 3 B, including Raspberry Pi Zero, Pi 3 B+，Pi 4 B.

- Several improvements have been made since the original respeaker mic array v1. 0 . Pick up voices from far awayfar-field voice capture enables you to capture and understand requests from up to 5m away.
Far-field voice capture/support USB Audio Class 1. 0 uac 1. 0 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.
Improved voice audio qualityReduces environmental voice echo with de-reverberation，Remove current audio output with AEC. The first thing you may notice is the reduction of microphones. Focus on the right voicedoa 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.
