Better Sound Processing

Designed for voice interface applications, the ReSpeaker Core v2.0 effortlessly processes speech algorithms in full documents. Based around the Rockchip RK3229, it uses a quad-core ARM Cortex A7, which can process at speeds up to 1.5GHz. The six microphones have an array of speech algorithms such as direction of arrival, beamforming, and acoustic echo cancellation. The core runs a GNU/Linux operating system (Debian), meaning it benefits from a powerful and frequently updated community of existing software tools for development and testing.
