About OpenVoiceOS
OpenVoiceOS is a voice AI platform, described on its homepage as community-driven and open source, for building voice-controlled interfaces across devices. The homepage describes a customizable UI and a focus on privacy and security. It is installed with Docker or a Python virtual environment, and the project also offers a prebuilt image for Raspberry Pi and Mycroft devices. It began as MycroftOS and was renamed to avoid trademark issues. The project says it is independent of Mycroft but keeps its components compatible with it.
The platform uses a plugin-based design for speech recognition and text-to-speech. The default speech-to-text setup uses online services, and some text-to-speech options also rely on external services such as Google TTS and Amazon Polly. Local options are available, including Vosk, Mozilla DeepSpeech and Mimic3. Core components do not require a backend internet server by default, but individual skills and plugins may need internet access.
