Open Voice OS

What OpenVoiceOS is

OpenVoiceOS (OVOS) is a community-driven open source voice AI platform, continuing the Mycroft project. It lets you build custom voice-controlled interfaces on hardware such as Raspberry Pi, Mycroft devices and Linux desktops, with a modular architecture (ovos-core, ovos-listener, ovos-messagebus) and pluggable speech recognition and text-to-speech engines.

It emphasises local processing of voice data rather than cloud upload.

What you can do with it

• Run a voice assistant on your own hardware
• Add voice control to home automation
• Swap STT and TTS engines per project
• Develop custom voice skills

Who it is for

• Open source enthusiasts and voice AI developers
• Privacy-focused local deployment users
• Smart hardware and home automation hobbyists

What to watch out for

• It is a developer platform: expect setup, hardware and configuration work, not a consumer product
• Local processing still depends on which engines you plug in; some may call external services
• Community projects move unevenly, so check release activity before standardising on it
• Skills and plugins come from the community and deserve review before use
