FAQ

How did Open Voice OS start and what is its relationship with Mycroft?

Open Voice OS began as MycroftOS and was later renamed to avoid trademark issues. While both projects are independent, Open Voice OS initially focused on bundling Mycroft-core and now maintains an enhanced reference fork with extra functionality, aiming for compatibility with Mycroft components.

Is Open Voice OS free to use and what license does it use?

Yes, Open Voice OS is completely free and open source, released under the Apache License 2.0. This allows for personal or commercial use, modification, distribution, and contribution to the project.

What hardware does Open Voice OS support and can it work offline?

Open Voice OS supports various hardware platforms including Raspberry Pi models (3B, 3B+, 4, Zero 2), Mark I and Mark II devices, Linux desktops/laptops, and Docker containers. While ovos-core doesn't require an internet server, the default STT engine needs an internet connection, though self-hosted offline options like Vosk or Mozilla DeepSpeech are available.
