      Description

      Seeed’s ReSpeaker Core v2.0 is designed for voice interface applications. It is based on the Rockchip RK3229, a quad-core ARM Cortex A7, running up to 1.5GHz, with 1GB RAM. The board features a six microphone array with speech algorithms including DoA (Direction of Arrival), BF (Beamforming), AEC (Acoustic Echo Cancellation), etc.


      ReSpeaker Core v2.0 runs a GNU/Linux operating system (Debian). It benefits from a powerful and active community allowing for the use of existing software and tools for development, testing, and deployment, enabling rapid product development.


      ReSpeaker Core v2.0 is designed as a feature rich development board for businesses to evaluate. To this end the board consists of two main sections, the first being the center core module containing the CPU, Memory (RAM), and PMU. The second section is the outer carrier board which contains the peripherals such as the eMMC, connectors, and wireless connectivity components. Either section or both can be customized through Seeed’s customization services.

      What method is used for DoA? Is source code provided for this function?

      Hi Jerry~ The DoA arithmetic is provided by the third-party partner. Unfortunately, it is not an open source arithmetic. Regards

      There is an open source implementation of DoA which is based on GCC-PHAT. See https://github.com/respeaker/mic_array

      Is the device recognized as an input audio device if connected via USB to a PC running Debian? Can it be used with the Snips platform?

      Hi there~ The ReSpeaker Core v2.0 runs a Linux system. And it can not be recognized as an audio input. To meet your needs, we firmly recommend the ReSpeaker Mic Array v2.0. This one is really good, i like it myself. However it is not available now, if you need one now, you can consider our ReSpeaker Mic Array v1.0. Please stay tune with us.=====================================================================V2.0--- http://wiki.seeedstudio.com/ReSpeaker_Mic_Array_v2.0/v1.0--- https://www.seeedstudio.com/ReSpeaker-Mic-Array-Far-field-w%2F-7-PDM-Microphones--p-2719.html
