Supported Devices and Platforms

Open Voice OS runs on multiple devices and platforms, including the Raspberry Pi and all major Linux distributions. The platform specifically supports Raspberry Pi 3, 4, and 5 models, as well as the Mycroft device.

Installation can be performed through Python Virtual Environment or Docker, with installation guided by an installer script. The script can be executed with the command:

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"

The platform offers a prebuilt image specifically designed for Raspberry Pi and Mycroft devices, ideal for embedded systems, low-spec headless devices, and small touch-friendly screens.

During its development, the project was known as MycroftOS before renaming to OpenVoiceOS to address trademark issues. The software initially focused on bundling Mycroft-core and creating companion software. However, due to community contribution challenges, it now maintains an enhanced reference fork of Mycroft-core with additional functionality while keeping companion software compatible with Mycroft's dev branch.

The project maintains close ties with other FOSS voice technology initiatives. HiveMind offers an extension of OpenVoiceOS capabilities across multiple devices, while TigreGótico serves as the official R&D partner, providing enterprise support. Development contributions are particularly welcome, with the platform's success relying heavily on community involvement across all technical aspects.

Installation and Development

OpenVoiceOS offers two primary installation methods: Python Virtual Environment and Docker. The installer script for Python Virtual Environment installation can be run with the command:

Technical Functionality

The platform's core functionality operates in an offline mode by default, with the primary voice recognition engine (STT) requiring an internet connection for operation. Users can take advantage of local speech recognition alternatives that eliminate internet dependency, though these options may not offer the same feature set as the default service. Skills and plugins can vary in their connectivity requirements, with some functionality remaining available even when an internet connection is not established.

The platform's modular architecture allows users to enable or disable various features based on their specific needs. Some skills function entirely offline, providing users with basic voice control capabilities without network dependence. This design choice enables the system to maintain operation even in environments where internet connectivity is unreliable or unavailable.

Community and Contributions

The platform's development relies heavily on contributions from developers across multiple technical areas, including front-end interfaces, backend services, machine learning, and voice recognition.
