We received much feedback from ReSpeaker Core v1 users and have added many requested features. Different from the original board this SBC is running Debian* with an onboard microphone array and software based voice enhancement algorithms.

A High Performance Platform

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 in our 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). Our BF and AEC algorithms are provided by Alango, a professional audio DSP company used in the automotive industry.
