# Voice Assistant
Offline voice assistant pipeline, powered by Rhasspy.
## Architecture
Rhasspy is a **central server** + **satellite microphones**. The server runs the STT (Kaldi / Vosk / DeepSpeech), intent recognition (Snips, Rasa, or simple regex), and TTS (Mozilla TTS, Festival, Larynx). Satellites are small audio capture clients (Pi Zero + ReSpeaker hat, or a Mac/Linux running rhasspy-microphone-cli) that stream audio to the server over MQTT or HTTP.
## Features
- Wake word: Porcupine / Mycroft Precise / Snowboy
- STT: Kaldi / Vosk / DeepSpeech / Pocketsphinx — all local
- Intent recognition: regex / fst / fuzzywuzzy / Mycroft Adapt / Rasa NLU
- TTS: nanoTTS / Mozilla TTS / Larynx / OpenTTS / MaryTTS / Festival / picoTTS / Wavenet
- Home Assistant + Node-RED intent handlers
- Multi-language
## ⚠️ This container is the brain, not the ear
The cloud container has no microphone. To actually speak commands, you need a satellite device on your network — typically a small board next to where you live. See the Rhasspy docs for satellite setup.
## Packaging
Thin wrapper around the official `rhasspy/rhasspy` image. Profiles + downloaded models live under `/profiles`. Web UI at `/`.
