Seeed Studio Voice control system ReSpeaker Core v2 Bulk

Seeed Speaker Core v2

With the ReSpeaker Core v2.0, developers can create powerful and impressive voice and sound interfaces. The ReSpeaker Core v2.0 is suitable as a basis for intelligent support and in response to ambient noise. It was developed with the idea that developers deserve to have many options.

A high-performance platform
of the ReSpeaker Core v2.0 is powered by the Axol Core module with the Rockchip RK3229 Quad-Core Cortex-A7 with a Mali 400MP GPU, 1 GB DDR3 RAM and a PMU. At Kern is the Debian operating system. This gives developers much more flexibility and resources to build their projects.
Peripherals around the Kern include a Kingston 4GB eMMC that integrates the operating system, a WiFi/BLE module, USB, Grove and HDMI ports, the integrated 6-mic array, an LED ring and much more.

An integrated 6-mic array with professional speech enhancement algorithms
New to our ReSpeaker product line is a software-based approach to speech enhancement. With the more powerful Axol Core, the Core v2.0 can process the audio data received via the 6 remote field microphones in real time. The ReSpeaker Core v2.0 supports noise suppression (NS), keyword wakeup, arrival direction (DoA), beamforming (BF) and acoustic echo cancellation (AEC). Our BF and AEC algorithms are provided by Alango, a professional audio DSP company used in the automotive industry.

Audio and video output
The audio output is via the 3.5 mm audio socket (output only) as well as via a JST two-pin connection and Bluetooth. The ReSpeaker Core v2.0 supports video output via HDMI * and allows developers to create extensive visual interfaces for interfacing with a voice interface.

Adjustment
of the ReSpeaker Core v2.0 can now be adjusted. To enable rapid adaptation, we have separated the Kern and the Peripherals. If a project requires a custom microphone array solution, we can quickly design and manufacture to scale. Contact us at iot@seeed.cc for more information.
