Open Voice Os Q&A

Open Voice OS started as MycroftOS. Over time, more Mycroft community members joined the project, and it was renamed to OpenVoiceOS to avoid trademark issues. Initially, Open Voice OS focused on bundling Mycroft-core and creating companion software, but due to contributions not being accepted upstream, we now maintain an enhanced reference fork of Mycroft-core with extra functionality while keeping all companion software Mycroft-core (dev branch) compatible. You can think of Open Voice OS as the unsanctioned 'Mycroft Community Edition.'

Both projects are fully independent. Initially, Open Voice OS focused on wrapping Mycroft-core with a minimal OS, but as both projects matured, Open Voice OS-core was created to include extra functionality and make Open Voice OS development faster and more efficient. Open Voice OS has been committed to keeping our components compatible with Mycroft, and many of our changes are submitted to Mycroft to include in their projects at their discretion.

Yes! Open Voice OS is completely free and open source. It's released under the Apache License 2.0, which means you can: Use it for personal or commercial purposes, Modify and distribute it, Contribute back to the project. We do appreciate donations to help sustain the project, but they are entirely optional.

By default, ovos-core does not require a backend internet server to operate. Some skills can be accessed (via command line) entirely offline. The default speech-to-text (STT) engine currently requires an internet connection, though some self-hosted, offline options are available. Individual skills and plugins may require internet, and most of the time you will want to use those for a full experience.

Open Voice OS can run on a variety of hardware platforms, including: Raspberry Pi models (3B, 3B+, 4, Zero 2), Mark I and Mark II devices, Linux desktops and laptops, Docker containers. Check our downloads page for specific images and installation instructions.
