ReSpeaker Mic Array - Far-field w/ 7 PDM Microphones

NOTE:

The New version is available now, please ckick The ReSpeaker Mic array v2.0 to check.

The ReSpeaker Mic Array can be stacked (connected) right onto the top of ReSpeaker Core to significantly improve the voice interaction experience. It is developed based on the XVSM-2000 Smart Microphone from XMOS. The board integrates 7 PDM microphones to help enhance ReSpeaker's acoustic DSP performance to a much higher level. With the Mic Array attached onto the top of the ReSpeaker Core, ReSpeaker is now able to:

• Far-field Voice Capture

• Acoustic Source Localization

• Beamforming

• Noise Suppression

• De-reverberation

• Acoustic Echo Cancellation

• XMOS microcontroller with 16 cores inside

• 7 high performance digital microphones

• Supports Far-field Voice Capture (up to 10m)

• Supports Beamforming, Acoustic Source Localization, Nosie Suppression, De-reverberation and Acoustic Echo Cancellation

• 12 programmable RGB LED indicators

• Microphones: ST MP34DT01-M

• Sensitivity: -26 dBFS (Omnidirectional)

• Acoustic overload point: 120 dBSPL

• SNR: 61 dB

• Power Supply: 5V DC from Micro USB or expansion header

• Dimensions: 70mm (Diameter)

• Weight: 15.25g

Here is a video from Parvinder Yadav, it teaches how to use ReSpeaker Mic Array - Far-field w/ 7 PDM Microphones to make google assistant. We really appreciate Parvinder's contribution to the community and hope this video can be a good help for you.
