Seeed Studio ReSpeaker Mic Array v2.0 Microphones XMOS’s XVF-3000

#ad
seeed studio #ad - Far-field voice capture/support USB Audio Class 1. 0 uac 1. 0 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.

The first thing you may notice is the reduction of microphones. Improved voice audio qualityReduces environmental voice echo with de-reverberation,Remove current audio output with AEC. 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. With the improved performance of the xmos xvf-3000, we’ve been able to deliver increased performance with fewer microphones, including the improved full duplex AEC, and thus a lower cost.

Seeed Studio ReSpeaker 4-Mic Array for Raspberry Pi, Raspberry Pi Microphone

#ad
seeed studio #ad - 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.

Respeaker 4-mic array does not have audio output. This raspberry pi microphone support all raspberry pi models, Raspberry Pi 1 B+, Pi 2 B, including Raspberry Pi Zero, Pi 3 B, Pi 3 B+,Pi 4 B. 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. 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, estimate doadirection of Arrival and show the direction via LED ring, Raspberry Pi would have ability to do VADVoice Activity Detection, just like Amazon Echo or Google Home. 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 .
