The ReSpeaker Core v2.0 allows developers create powerful and impactful voice and sound interfaces. Suitable both as a base for smart assistance as well as responding to environmental sounds, the ReSpeaker Core v2.0 was designed with the idea that developers deserve to have many options available to them.

The ReSpeaker Core v2.0 is powered by the Axol Core module, featuring the Rockchip RK3229 Quad-Core Cortex-A7 with a Mali 400MP GPU, 1GB of DDR3 RAM, and a PMU. The core runs the Debian OS. This provides developers with much more flexibility and resources to create their projects.

Around the core are peripherals including a Kingston 4GB eMMC to enable the OS to run onboard, a WiFi/BLE module, USB, Grove, and HDMI connectors, the on board 6-mic array, LED ring, and more.

New to the ReSpeaker product line is a software based approach to voice enhancement. The more powerful Axol Core allows the Core v2.0 to process the audio received through the 6 far field microphones in real-time. The ReSpeaker Core v2.0 supports Noise Suppression (NS), Keyword Wakeup, Direction of Arrival (DoA), Beam-forming (BF), Acoustic Echo Cancellation (AEC). The BF and AEC algorithms are provided by Alango, a professional audio DSP company used in the automotive industry.

Respeaker core v2

I really really like respeaker and cool components! But the Linux software that comes with respeaker needs a lot of work.... the 2/3 apps they promote work ok but lots of other stuff does not This makes it hard to use respeaker in the long term This is Seeed problem but active software community is critical
