Open Voice OS

Overview

Build and deploy customizable AI voice assistants across devices.

Open Voice OS is an open-source, community-driven voice AI platform for building customizable voice assistants across embedded, single-board, and desktop systems. It supports Raspberry Pi, Mark I/II hardware, Linux desktops, and Docker containers for multi-platform deployment.

A plugin-based STT and TTS architecture enables online and self-hosted offline options (e.g., Vosk, Mimic3) for speech recognition and synthesis. Configurable wake words, a customizable UI, and extensible skills enable smart home control, media playback, timers, and custom voice workflows.

Installation options include prebuilt images for low-spec devices, Docker containers, and a Python virtual environment for development. The project emphasizes privacy and security and maintains compatibility with Mycroft components while enabling independent contributions.

Use Cases

• Build a privacy-first home voice assistant on a Raspberry Pi using Open Voice OS without relying on cloud services, leveraging offline STT/TTS, configurable wake words, and self-hosted models to control smart-home devices and run local automations.
• Deploy a containerized, offline voice interface for industrial or embedded systems with Open Voice OS to run on single-board computers or Docker, add custom skills for equipment monitoring and alerts, and keep all audio and data on-premises for compliance-sensitive environments.
• Create a multilingual, hands-free Linux desktop assistant for developers and power users using Open Voice OS by integrating plugin-based speech-to-text and speech synthesis, extending skills for task automation and documentation lookup, and self-hosting models for low-latency, private voice interactions.
