https://github.com/rhasspy/wyoming-piper is a fast, local neural text to speech system that sounds great and is optimized for the Raspberry Pi 4. This container provides a Wyoming protocol server for Piper.

Supported Architectures

We utilise the docker manifest for multi-platform awareness. More information is available from docker https://distribution.github.io/distribution/spec/manifest-v2-2/#manifest-list and our announcement here.

Simply pulling lscr.io/linuxserver/piper:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Application Setup

For use with Home Assistant Assist, add the Wyoming integration and supply the hostname/IP and port that piper is running add-on."

For more information see the https://github.com/rhasspy/wyoming-piper,

Read-Only Operation

This image can be run with a read-only container filesystem. For details please read the docs.

Usage

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

[!NOTE] Unless a parameter is flagged as 'optional', it is mandatory and a value must be provided.

docker-compose (recommended, click here for more info)

docker cli (click here for more info)

bash
docker run -d \
  --name=piper \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Etc/UTC \
  -e PIPER_VOICE=en_US-lessac-medium \
  -e LOCAL_ONLY= `#optional` \
  -e PIPER_LENGTH=1.0 `#optional` \
  -e PIPER_NOISE=0.667 `#optional` \
  -e PIPER_NOISEW=0.333 `#optional` \
  -e PIPER_SPEAKER=0 `#optional` \
  -e NO_STREAMING= `#optional` \

  -v /path/to/piper/data:/config \
  --restart unless-stopped \
  lscr.io/linuxserver/piper:latest

Parameters

Containers are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

bash
-e FILE__MYVAR=/run/secrets/mysecretvariable

Will set the environment variable MYVAR based on the contents of the /run/secrets/mysecretvariable file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id your_user as below:

bash
id your_user

Example output:

text
uid=1000(your_user) gid=1000(your_user) groups=1000(your_user)

Support Info

• Shell access whilst the container is running:

  bash
  docker exec -it piper /bin/bash
  

• To monitor the logs of the container in realtime:

  bash
  docker logs -f piper
  

• Container version number:

  bash
  docker inspect -f '{{ index .Config.Labels "build_version" }}' piper
  

• Image version number:

  bash
  docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/piper:latest
  

Updating Info

Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (noted in the relevant readme.md), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.

Below are the instructions for updating containers:

Via Docker Compose

• Update images:

  • All images:

    bash
    docker-compose pull
    

  • Single image:

    bash
    docker-compose pull piper
    

• Update containers:

  • All containers:

    bash
    docker-compose up -d
    

  • Single container:

    bash
    docker-compose up -d piper
    

• You can also remove the old dangling images:

  bash
  docker image prune
  

Via Docker Run

• Update the image:

  bash
  docker pull lscr.io/linuxserver/piper:latest
  

• Stop the running container:

  bash
  docker stop piper
  

• Delete the container:

  bash
  docker rm piper
  

• Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your /config folder and settings will be preserved)

• You can also remove the old dangling images:

  bash
  docker image prune
  

Image Update Notifications - Diun (Docker Image Update Notifier)

[!TIP] We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.

Building locally

If you want to make local modifications to these images for development purposes or just to customize the logic:

bash
git clone https://github.com/linuxserver/docker-piper.git
cd docker-piper
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/piper:latest .

The ARM variants can be built on x86_64 hardware and vice versa using lscr.io/linuxserver/qemu-static

bash
docker run --rm --privileged lscr.io/linuxserver/qemu-static --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
