What it is

OpenVoiceOS (OVOS) is the modular reboot of Mycroft. It separates ASR, TTS, intent parser, and skills into pluggable layers, so you can pair Vosk with Whisper-server with a Llama-based intent handler.

Best for: Self-hosting a privacy-respecting voice assistant on a Raspberry Pi 4/5 with no cloud dependency.
Watch out for: Setup is hobbyist-grade; documentation patchy; speech-to-text quality depends on the chosen plug-in (Vosk, Whisper, etc.).
