The ReSpeaker Project


The website is still under construction

The ReSpeaker project provides hardware components and software libraries to build voice enabled device.


The hardware components include I2S microphone array for Raspberry Pi, USB microphone array for Linux/Windows/macOS, standalone ReSpeaker Core v1.0 & v2.0.
