Rhasspy should run in a variety of software environments, including:


The easiest way to try Rhasspy is with Docker. To get started, make sure you have Docker installed:

curl -sSL | sh

and that your user is part of the docker group:

sudo usermod -a -G docker $USER

Be sure to reboot after adding yourself to the docker group!

Next, start the Rhasspy Docker image in the background:

docker run -d -p 12101:12101 \
      --restart unless-stopped \
      -v "$HOME/.config/rhasspy/profiles:/profiles" \
      --device /dev/snd:/dev/snd \
      synesthesiam/rhasspy-server:latest \
      --user-profiles /profiles \
      --profile en

This will start Rhasspy with the English profile (en) in the background (-d) on port 12101 (-p) and give Rhasspy access to your microphone (--device). Any changes you make to your profile will be saved to ~/.config/rhasspy.

Once it starts, Rhasspy's web interface should be accessible at http://localhost:12101. If something went wrong, trying running docker with -it instead of -d to see the output.

If you're using docker compose, add the following to your docker-compose.yml file:

    image: "synesthesiam/rhasspy-server:latest"
    restart: unless-stopped
        - "$HOME/.config/rhasspy/profiles:/profiles"
        - "12101:12101"
        - "/dev/snd:/dev/snd"
    command: --user-profiles /profiles --profile en

Updating Docker Image

To update your Rhasspy Docker image, just run:

docker pull synesthesiam/rhasspy-server:latest

on your Rhasspy server and restart the Docker container. This may require running something like:

docker rm <container-name>

before doing a docker run...

The second easiest way to install Rhasspy is as a add-on. Follow the installation instructions for before proceeding.

To install the add-on, add my Hass.IO Add-On Repository in the Add-On Store, refresh, then install the "Rhasspy Assistant" under “Synesthesiam Hass.IO Add-Ons” (all the way at the bottom of the Add-On Store screen).

Synesthesiam add-on store

NOTE: Beware that on a Raspberry Pi 3, the add-on can take 10-15 minutes to build and around 1-2 minutes to start.

Watch the system log for a message like Build 8e35c251/armhf-addon-rhasspy:2.11 done. If the “Open Web UI” link on the add-on page doesn’t work, please check the log for errors, wait a minute, and try again.

Before starting the add-on, make sure to give it access to your microphone and speakers:

Updating Hass.IO Add-On

You should receive notifications when a new version of Rhasspy is available for Hass.IO. Follow the instructions from Hass.IO on how to update the add-on.

Virtual Environment

Rhasspy can be installed into a Python virtual environment, though there are a number of requirements. This may be desirable, however, if you have trouble getting Rhasspy to access your microphone from within a Docker container. To start, clone the repo somewhere:

git clone

Then run the and scripts (assumes a Debian distribution):

cd rhasspy/

Once the installation finishes (5-10 minutes on a Raspberry Pi 3), you can use the script to start Rhasspy:

./ --profile en

If all is well, the web interface will be available at http://localhost:12101

Updating Virtual Environment

To update your Rhasspy virtual environment to the latest version, run:

git pull origin master

in your rhasspy directory, and then update your Python dependencies:

source .venv/bin/activate
pip3 install -r requirements.txt

You should also re-build the web interface:

  1. Install yarn on your system
  2. Run yarn install && yarn build in the rhasspy directory
  3. Restart any running instances of Rhasspy

Running as a Service

Once installed, Rhasspy can be run as a systemd service. An example unit file is available (thanks UnderpantsGnome):


ExecStart=/bin/bash -lc './ --profile <LANGUAGE>'




  • Replace /home/<USER>/path/to/rhasspy with the full path to your Rhasspy installation (where is).
  • Replace <LANGUAGE> with your profile language (e.g., en)

Create a file named rhasspy.service in the /home/<USER>/.config/systemd/user directory (you may need to create the directory itself). Once the file has been saved, run:

systemctl --user daemon-reload

Then, you can start Rhasspy with:

systemctl --user start rhasspy

If you'd like Rhasspy to start on boot, run:

systemctl --user enable --now rhasspy

Build From Source

The script uses pre-compiled binaries for Rhasspy's required tools:

The attempts to build all of these tools from source. The binary artifacts (command-line tools, shared libraries) are installed into the bin and lib directories of a Python virtual environment. The script automatically adds these directories to PATH and LD_LIBRARY_PATH before starting Rhasspy.

Swap Size

On low memory devices like the Raspberry Pi, building the tools above can quickly consume the entire RAM. Before building, it's highly recommended that you increase the available swap space by several gigabytes:

  1. Edit /etc/dphys-swapfile
  2. Change CONF_SWAPSIZE to something large, like 2048 (2GB)
  3. Reboot


You can skip building Kaldi if you plan to just use Pocketsphinx for speech recognition.

Updating Source Install

Follow the same instructions as updating a virtual environment.
