According to official README file, "it probably operates on other *nx distributions." It is known to work on a variety of Linux distributions including Debian, Ubuntu and Raspbian. Mycroft Precise is fully open source and can be trained to recognize anything from a name to a cough. In addition to Picovoice, we provide limited support for Mycroft Precise - an open-source real-time keyword detection package. Open-source Keyword detection with Mycroft Precise ¶ Build using familiar languages and frameworks. Cross-Platform: Design once, deploy anywhere.It outperforms cloud-based alternatives by wide margins. Accurate: Resilient to noise and reverberation.Zero Latency: Edge-first architecture eliminates unpredictable network delay.Reliable: Runs without needing constant connectivity.Private: Everything is processed offline.It enables creating voice experiences similar to Alexa and Google. Picovoice is an end-to-end platform for building voice products on your terms.

Seeed has partnered with Picovoice to bring Speech Recognition solution at the edge using ReSpeaker 2-Mic Pi HAT for developers. Build a unified AI strategy around your brand and products with our speech recognition and Natural-language understanding (NLU) technologies. Picovoice enables enterprises to innovate and differentiate rapidly with private voice AI. 3.5mm AUDIO JACK: for connecting headphone or speaker with 3.5mm Audio Plug.JST 2.0 SPEAKER OUT: for connecting speaker with JST 2.0 connector.GPIO12: Grove digital port, connected to GPIO12 & GPIO13.I2C: Grove I2C port, connected to I2C-1.POWER: Micro USB port for powering the ReSpeaker 2-Mics Pi HAT, please power the board for providing enough current when using the speaker.Raspberry Pi 40-Pin Headers: support Raspberry Pi Zero, Raspberry Pi 1 B+, Raspberry Pi 2 B, Raspberry Pi 3 B and Raspberry Pi 3 B+.RGB LED: 3 APA102 RGB LEDs, connected to SPI interface.MIC_Land MIC_R: 2 Microphones on both sides of the board.BUTTON: a User Button, connected to GPIO17.Raspberry Pi compatible(Support Raspberry Pi Zero and Zero W, Raspberry Pi B+, Raspberry Pi 2 B, Raspberry Pi 3 B, Raspberry Pi 3 B+, Raspberry Pi 3 A+ and Raspberry Pi 4).What is more, 3.5mm Audio Jack or JST 2.0 Speaker Out are both available for audio output. There are 2 microphones on both sides of the board for collecting sounds and it also provides 3 APA102 RGB LEDs, 1 User Button and 2 on-board Grove interfaces for expanding your applications. The board is developed based on WM8960, a low power stereo codec. This means that you can build a more powerful and flexible voice product that integrates Amazon Alexa Voice Service, Google Assistant, and so on. To fix random system hangs due to a small amount of RAM you can enable optimized swapping according to my article Effective Raspberry Pi ZRAM usage.ReSpeaker 2-Mics Pi HAT is a dual-microphone expansion board for Raspberry Pi designed for AI and voice applications.
RASPBERRY CODEC 720P
Note that Raspberry Pi 3 can smoothly play max 720p video in this mode. If you want to play HTML5 videos set GPU memory to 256 MB and disable h264ifi extension.
RASPBERRY CODEC 1080P
So, we need to set the flag: #enable-gpu-rasterization = Enabledįor Raspberry Pi 3 (128 MB GPU memory) my updated result is smooth 1080p youtube playing with 17% CPU load. So leave it in the default "Disabled" state. Thanks to Nghia Nguyen for feedback, the flag "#ignore-gpu-blacklist = Enabled" is also not needed, because the latest Chromium has changes in the rendering engine.

RASPBERRY CODEC UPDATE
Update : For the latest version of the Chromium browser, I have a lot of settings that, as I mentioned earlier, are no longer needed (Thanks to the developers of Chromium). Then, open Chromium browser and write in address line:
RASPBERRY CODEC INSTALL
Sudo apt-get install mesa-vdpau-drivers -y We need installed some libraries to get Chromium's ability to use Raspberry Pi GPU: Sudo apt-get update sudo apt-get dist-upgrade -y Make sure we have 128 Mb shared GPU memory and updated system: So, can we have smooth fullscreen video in Chromium browser? Yes, we can! If we want to have exellent fullscreen video playback we need to use special programs, like Minimal Kiosk Browser which use OpenMax interface for media processing on the VideoCore IV GPU. This ability is not implemented in regular Raspbian image yet, so I decide to write this topic.Ĭhromium browser, the default browser in last Raspbian, was not developed for using hardware acceleration of the ARM GPU's. Its VideoCore GPU has a very interesting ability to make web surfing more smooth and comfortable. The Raspberry Pi is a tiny singleboard computer with a great potential.
