The ReSpeaker Project
Note
The website is still under construction
The ReSpeaker project provides hardware components and software libraries to build voice enabled device.
Hardware
The hardware components include I2S microphone array for Raspberry Pi, USB microphone array for Linux/Windows/macOS, standalone ReSpeaker Core v1.0 & v2.0.
Microphone Array
| USB 4 Mic Array | 2 Mic Array for Pi | 4 Mic Array for Pi | 4 Linear Mic Array for Pi | 6 Mic Array for Pi | |
|---|---|---|---|---|---|
| Microphones | 4 | 2 | 4 | 4 | 6 |
| Shape | circular | linear | square | linear | hexagon |
| Interface | USB | I2S | I2S | I2S | I2S |
| RGB LEDs | 12 | 3 | 12 | NA | 12 |
| Audio Output | Mono | Stereo | NA | Stereo | Stereo |
| Note | built-in algorithms |
If you are looking for a custom shape mic array, you may want to try Seeed's Fusion service to design a new one based on our design. It should be easy.
