## Overview
Open Voice OS is an open-source, community-driven voice AI platform designed for creating custom voice-controlled interfaces across multiple devices. It emphasizes privacy and security by operating offline, giving users complete control over their data. The platform supports various hardware options, from embedded headless devices to single-board computers with screens, making it ideal for building DIY smart speakers. What distinguishes Open Voice OS is its modular, plugin-based architecture that allows developers to choose from multiple speech-to-text (STT) engines like Vosk and DeepSpeech, text-to-speech (TTS) options including Mimic3 and Google TTS, and custom skill plugins. The platform serves as an experimental playground for voice AI technologies and serves as a bridge for developers testing features before contributing to upstream Linux-based open-source voice assistant projects. One limitation is that, as a community-driven project, the support and documentation may be less comprehensive than commercial alternatives.
