What it is

Rhasspy is the canonical offline voice assistant for Home Assistant. It chains wake word (Porcupine, openWakeWord, Snowboy) → ASR (Kaldi / Vosk / Whisper) → intent recognition → Home Assistant action. Now maintained by Nabu Casa.

Best for: Home Assistant users who want voice control with zero cloud traffic and full control over wake-word and ASR.
Watch out for: Setup is YAML-heavy; non-trivial to tune for a non-developer; voice quality depends on chosen backend (Kaldi, Pocketsphinx, Vosk, Whisper).
