Server for wikispeech TTS

Prerequisites:

git clone https://github.com/stts-se/wikispeech-server.git
cd wikispeech-server
sudo apt install opus-tools python3-pip
sudo pip3 install -r requirements.txt

mkdir wikispeech_server/tmp

Normally, python3-setuptools should be installed automatically as a dependency for python3-pip, but some cases have been reported where you need to install this separately (debian-9.1):

sudo apt install python3-setuptools

Usage:

python3 bin/wikispeech

Configuration:

For local configuration, make a copy of wikispeech_server/default.conf, name it <username>-<hostname>.conf, and edit it as needed.

The file contains settings for:

• Server
  • server port (default: 10000)
  • log_level (default: warning)
  • logger (default: stderr, possible settings: stderr, stdout, syslog, filename)
  • flask_debug_mode: python flask setting to reload when files are edited. (default: False)
• Voice config
  • config_files_location: Folder for config files (default: wikispeech_server/conf)
  • config_files: A list of voice config files to load
• Audio settings
  • audio_tmpdir: output directory for soundfiles. This directory needs to exist. (default: ./wikispeech_server/tmp)
• Services
  • lexicon: url to lexicon server. (default: http://localhost:8787)
  • mapper: url to symbol set mapper server. (default: http://localhost:8771)
  • marytts: url to marytts server. (default: http://localhost:59125/process)
  • ahotts: various configs for ahotts server. (default: http://localhost:1200)
• Tests
  • run_startup_test: Run or don't run a lot of tests - they may fail if configuration is incorrect, or lexicon/marytts servers are not found. (default: True)
  • quit_on_error: Quit if a test fails. (default: False)

To test the config file, the script can be run with a config file as argument:

python3 bin/wikispeech <config-file>

For developers:

If you are developing for Wikispeech, and need to make changes to this repository, make sure you run a test build using build_and_test.sh before you make a pull request. Don't run more than one instance of this script at once, and make sure no wikispeech servers are already running on the default ports.

Test:

google-chrome test.html

(may not work to load the audio, depends on setup)

google-chrome "http://localhost:10000/"

(for usage information)

google-chrome "http://localhost:10000/?lang=sv&input=Ett+test"

(example api call)

Documentation:

started in https://github.com/stts-se/wikispeech-server/wiki

Apache setup:

1. (optional - for access through apache)

Link the audio file directory in <webroot>, as defined in default.conf or your local configuration file:

$ cd <webroot>; sudo ln -s <audio_tmpdir> <audio_url_prefix>

example:

$ cd /var/www/html; sudo ln -s ~/git/wikispeech-server/wikispeech_server/tmp/ audio

Audio files generated by the TTS should now be accessible through: http://localhost/audio/ and from outside at http://<HOSTNAME>/audio

2. (optional - to avoid unwanted access)

Disallow access to non-opus files by adding a .htaccess-file <audio_tmpdir> with the following content

<FilesMatch "\.*$">
  Deny from all
</FilesMatch>
<FilesMatch "\.opus$">
  Order deny,allow
  Allow from all
</FilesMatch>

Remove directory listing by adding a index.html file in <audio_tmpdir> with something like the following content:

This is a service to serve Wikispeech audio files. There is really never any reason to see this page.

To also display this page in the root directory (instead of apache default): $ cd /var/www/html/; sudo rm index.html; sudo ln -s audio/index.html

3. (optional - for access through apache)

To access the wikispeech server through apache: Add something like this to your apache config file (for example "/etc/apache2/sites-enabled/000-default.conf") and restart apache (for example with "sudo apache2ctl restart"). You may need to run "sudo a2enmod proxy" and "sudo a2enmod proxy_http" first.

ProxyPreserveHost On
ProxyPass         /wikispeech/  http://127.0.1.1:10000/
ProxyPassReverse  /wikispeech/  http://127.0.1.1:10000/
ProxyRequests     Off

ProxyPreserveHost On
ProxyPass /ws_service/ http://127.0.1.1:8787/
ProxyPassReverse /ws_service/ http://127.0.1.1:8787/
ProxyRequests Off

4. (optional - for testing through apache)

Link this directory in apache's document root, for example:

cd /var/www/html; sudo ln -s ~/git/wikispeech-server

Test:

google-chrome http://localhost:10000/test.html

google-chrome http://localhost:10000/workflow_demo/test.html
