Why Open Voice OS?

Community Driven

Powered by developers around the globe from various Linux and Foss communities, an open platform for developers interested in making cutting-edge voice assistance technology available to everyone.

Multi-platform

Embedded headless device or single board computers with screens to build a do-it-yourself smart speaker, Open Voice OS is the open community playground for all platforms to come and experiment at.

Experimental at Core

Have an experimental feature you want users to experience before landing them into any of the Linux-based open-source voice assistant projects upstream? Open Voice OS is the platform.

DIY

Open Voice OS being a community platform is open to all developers and contributors wanting to support a specific device or a platform.

Getting started

Installing OVOS couldn't be simpler! Just give our installer a try, and you're all set. We offer two main ways to install OVOS - Docker and Python.

Python Virtual Environment

If you are a developer, and would like to fiddle with the code, this is the way to go.

Docker

If you want a super stable and easy way to run OVOS, Docker is the way to go.

To get started, simply copy and paste the following command in your terminal:

sh -c "curl -s https://raw.githubusercontent.com/OpenVoiceOS/ovos-installer/main/installer.sh -o installer.sh && chmod +x installer.sh && sudo ./installer.sh && rm installer.sh"

Own a Raspberry Pi or Mycroft® Device ?

Our Prebuild Image is a stripped-down Linux OS designed to host the open-source voice assistant Open Voice OS, catering specifically to embedded systems, low-spec headless devices, and small touch-friendly screens.

Frequently Asked Questions

Find answers to the most common questions about Open Voice OS, its features, and how to get involved.

General

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.

Technical

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 uses a plugin-based architecture for both speech recognition (STT) and text-to-speech (TTS):

Speech Recognition (STT): The default configuration uses online services, but you can also set up local/offline options like Vosk or Mozilla DeepSpeech.

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.
