Description

The ReSpeaker Core v2.0 allows developers create powerful and impactful voice and sound interfaces. Suitable to use 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.

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. 


The Debian and Android is supported now, for more detail please check our wiki.



        


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.


An Onboard 6-Mic Array with Professional Voice Enhancement Algorithms


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.


An Open Software Ecosystem


We recognize that each project has different requirements and goals. As such we have worked to provide as much flexibility to developers as possible. Our quad-core solution allows us to run numerous software solutions. From the selection of algorithms, NLP services, smart assistants, operating systems, and more, we wish to support our users. If you have suggestions on what services you would like to see us officially support let us know on our forums, or if you enjoy the work yourself, submit a merge request to our github.


Audio and Video Output*


Audio output is available via the 3.5mm audio jack (output only), as well as a JST two pin connector and Bluetooth. The ReSpeaker Core v2.0 supports video output through HDMI* enabling developers to create rich visual interfaces to pair with a voice interface.


*GPU not fully implemented on Debian: 1080p video playback will be available July 2018. Android 8.1 will support 4k video on release.


Customization


The ReSpeaker Core v2.0 is ready for customization. To allow quick customization we separated the core and peripherals. If a project required a custom mic array solution we are able to quickly design and manufacture to help scale. Contact us at iot@seeed.cc to learn more.

I bought a ReSpeaker Core v2.0 and the DOA works awfully, I wrote to customer service a week ago and they still have not responded, does anyone have experience with the DOA measurements being too bad to be useful or should I send the product back and request a refund? I checked and all the microphones seem to be working well.

Hi there, please provide the mail address and we will search the database. Which mail address do you send to? How do you test the DOA? For the DOA, there are 2 ways, one is python, please refer to **http://wiki.seeedstudio.com/ReSpeaker_Core_v2.0/#open-source-solution**, the other is c++, please refer to **http://respeaker.io/librespeaker_doc/classrespeaker_1_1SnowboyMbDoaKwsNode.html**. thanks.

Hello, I wrote to techsupport@seeed.cc and I am testing the DOA using the python solution, more specifically the ns_kws_doa.py file with a small modification so it would print the direction of the sound and not only of the keyword (I tried to reproduce this https://www.youtube.com/watch?v=XivM-6PRgX8): def on_detected(keyword): print('detected {} at direction {}'.format(keyword, doa.get_direction())) while True: print('detected at direction {}'.format(doa.get_direction())) time.sleep(1)

Hi Jerry~ The DoA arithmetic is provided by the third-party partner. Unfortunately, it is not an open source arithmetic. Regards

There is an open source implementation of DoA which is based on GCC-PHAT. See https://github.com/respeaker/mic_array
