Find answers to the most common questions about Open Voice OS, its features, and how to get involved.
How did Open Voice OS start?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". |
What is the relationship between Open Voice OS and Mycroft?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. |
Is Open Voice OS free to use?Yes! Open Voice OS is completely free and open source. It's released under the Apache License 2.0, which means you can:
We do appreciatedonations to help sustain the project, but they are entirely optional. |
Does Open Voice OS work offline?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. |
What hardware does Open Voice OS support?Open Voice OS can run on a variety of hardware platforms, including:

Text-to-Speech (TTS):Multiple options are available including Mimic3 (local), Google TTS, Amazon Polly, and more. You can choose and configure these in your settings.
