raspOVOS

raspOVOS turns a Raspberry Pi into a private, open-source voice assistant. You flash an SD card, boot the Pi, and talk to it. No cloud account or subscription is needed, and no data leaves your home unless you choose it.

It is the flagship OpenVoiceOS experience: ready-made images with the whole OVOS stack. Wake word, speech-to-text, intent handling, skills, and text-to-speech come preinstalled, preconfigured, and tuned for Raspberry Pi hardware.

Choose your image

Three variants trade privacy/latency against hardware requirements, each available in ~12 languages:

Variant	STT	TTS	Needs	Best for
lite	public servers	public servers	Pi 3 might work, Pi 4 better	trying it out on older hardware
hybrid	public servers	on device	Pi 4	balanced daily driver
offline	on device	on device	Pi 4/5 with 4 GB+ RAM (8 GB best)	full privacy, no internet dependency

!!! note “About the public servers” They are hosted by volunteers on a best-effort basis. Latency and uptime vary. If you have a bigger machine on your network, you can self-host STT/TTS and point any variant at it.

Get started in three steps

1. Download an image from the releases page. Pick your variant and language.
2. Flash it to an SD card. Follow Flash your first image.
3. Boot and talk. See First boot & talking to OVOS.

Default credentials: user ovos, password ovos, hostname raspOVOS.

!!! warning Do not change the default username when flashing. The images expect the ovos user to exist.
