Open Voice OS

Open Voice OS is an open-source voice operating system and ecosystem designed to run voice assistants on a wide range of devices, from desktops and single-board computers to embedded hardware. Built around the Mycroft/OVOS technology stack, it provides a modular framework for speech recognition, text-to-speech, intent parsing, and skill management. Users can deploy a fully local voice assistant, integrate cloud services where desired, and customize wake words, skills, and user experience.

The project offers ready-made images for devices like the Mark II and various Raspberry Pi-based boards, along with a Plasma-based desktop environment and DIY build options. Developers can build and publish voice “skills” to handle tasks such as media playback, home automation, information queries, and device control. A strong focus on privacy, transparency, and community governance distinguishes Open Voice OS from proprietary assistants.
