ReSpeaker Core v2.0
ReSpeaker Core allows developers to create powerful and effective audio and audio interfaces. Suitable for responding to environmental sounds as well as being used as a basis for smart assistance, ReSpeaker Core v2.0 was designed with the idea that it deserves to have many options available to developers.
ReSpeaker Core v2.0 is powered by Axol Core module with Rockchip RK3229 Quad Core Cortex-A7 with Mali 400MP GPU, 1GB DDR3 RAM and PMU. Runs the core Debian operating system. This gives developers much more flexibility and resources to build their projects.
Around the core are peripherals such as a Kingston 4GB eMMC, a WiFi / BLE module, USB, Grove and HDMI connectors, built-in 6 microphone array, LED ring and more for on-board operation of the operating system.
New to the ReSpeaker product line is a software-based approach to sound enhancement. The more powerful Axol Core enables Core v2.0 to process sound received from 6 far field microphones in real time. ReSpeaker Core v2.0 supports Noise Suppression (NS), Keyword Wake, Direction of Arrival (DoA), Beam generation (BF), Acoustic Echo Cancellation (AEC). Our BF and AEC algorithms are provided by Alango, a professional audio DSP company used in the automotive industry.
