Extension:Wikispeech/Installing Speechoid

Speechoid is the text-to-speech backend of Wikispeech. It consists of a number of services controlled via Wikispeech-server. The Speechoid build pipeline use Blubber to create Docker images which is ment to be deployed on for instance a Kubernetes cluster, but there is also a Compose project ment for running locally, on development servers and small installations.

Please report any errors you encounter in the discussion of this wikipage.

= Prerequisits =

This guide is based on the setup used by the Wikispeech development team that use Ubuntu (18, 19 and 20) as workstations and Debian (10) server side.

Docker
https://docs.docker.com/engine/install/

Docker compose
https://docs.docker.com/compose/install/

Blubber
https://wikitech.wikimedia.org/wiki/Blubber/Download We strongly recommend using the prebuilt binary.

Make sure it's available in your $PATH, e.g. by copying it to /usr/local/bin.

Java JDK 11
The Mary TTS service require JDK 11. Not JDK 11 or greater, specifically JDK 11. Even though it's possible to build using a later version, our use of secure and limited Docker images via Blubber require us to download compatible Gradle (the build tool used by Mary TTS) and dependencies using JDK 11 to ensure there will be no further network access when starting Mary TTS from within the Docker container.

apt-get install openjdk-11-jdk

Make sure environment variable JAVA_HOME points at JDK 11.

export JAVA_HOME=/usr/lib/jvm/java-1.11.0-openjdk-amd64

= Building services =

Using the build script
The docker-compose project comes with a script that will download and build all services for you.

git clone https://github.com/karlwettin/wikispeech-docker-compose.git cd wikispeech-docker-compose ./create-all-images.sh

Manually
Each service lives in its own git repository at gerrit.wikimedia.org:

git clone "ssh://karlwettin@gerrit.wikimedia.org:29418/mediawiki/services/wikispeech/mary-tts" git clone "ssh://karlwettin@gerrit.wikimedia.org:29418/mediawiki/services/wikispeech/mishkal" git clone "ssh://karlwettin@gerrit.wikimedia.org:29418/mediawiki/services/wikispeech/pronlex" git clone "ssh://karlwettin@gerrit.wikimedia.org:29418/mediawiki/services/wikispeech/symbolset" git clone "ssh://karlwettin@gerrit.wikimedia.org:29418/mediawiki/services/wikispeech/wikispeech-server"

Each service contains a set of Blubber-helper scripts that downloads and prepares any dependency of the image.

cd some-service ./blubber-prepare.sh ./blubber-build.sh

= Starting Speechoid =

Using compose
The easiest way is to spin it up using docker-compose:

git clone https://github.com/karlwettin/wikispeech-docker-compose.git cd wikispeech-docker-compose ./run.sh

After a little while Wikispeech server should be available as an HTTP service on port 10000.

Manually
As of writing this documentation, there is no ready to go pipeline for starting up in other environments. Speechoid will, when ready for production, be deployed on a Kubernets cluster. Expect documentation about that here.

= Setting up on WMF Cloud VPS =

As of writing this documentation, there is a problem with the WMF Cloud VPS Debian 10 Buster images related to file system character encoding and aptitude. This cause problems when install java-ca-certificates package, resulting in not being able to download Gradle wrapper and dependencies for Mary TTS. You must therefore rather than building the docker images on the Cloud VPS instance do that on your local machine, extract (and compress) them, upload them to your Cloud VPS instance, and there install the uploaded image:

docker save wikispeech-mary-tts:lastest | gzip > wikispeech-mary-tts:latest.tar.gz docker save wikispeech-mishkal:lastest | gzip > wikispeech-mishkal:latest.tar.gz docker save wikispeech-pronlex:lastest | gzip > wikispeech-pronlex:latest.tar.gz docker save wikispeech-symbolset:lastest | gzip > wikispeech-symbolset:latest.tar.gz docker save wikispeech-server:lastest | gzip > wikispeech-server:latest.tar.gz scp -o "ProxyJump you@primary.bastion.wmflabs.org" wikispeech-mary-tts:latest.tar.gz you@your-instance.wmflabs:~/ ... ssh -J you@primary.bastion.wmflabs.org you@your-instance.wmflabs docker load -i wikispeech-mary-tts:latest.tar.gz ... cd wikispeech-docker-compose ./run.sh
