ReSpeaker 4-Mic Array for Raspberry Pi

$24.95

Sparkfun # DEV-14645

The ReSpeaker 4-Mic Array is a quad-microphone expansion board for Raspberry Pi designed for AI and voice applications. With the ReSpeaker, you will be able to build a more powerful and flexible voice project with your Raspberry Pi that integrates Amazon Alexa Voice Service, Google Assistant, and more!

The ReSpeaker is developed based on the AC108 IC, a highly integrated quad-channel ADC with I2S/TDM output transition for high definition voice capture. This HAT is also equipped with LED ring, which contains 12 APA102 programmable LEDs. That, combined with the four microphones mentioned beforehand, your Raspberry Pi will have the ability to do VAD (Voice Activity Detection), and estimate the DOA (Direction of Arrival), just like an Amazon Echo or Google Home.
