Usage
For all usage information, see the extension's help page.

Maintenance
Phonos does not automatically delete files that have become orphaned. Over time, these files can build up and needlessly occupy space on your file system. To assist with this problem, Phonos offers two maintenance scripts:

countOrphanedFiles.php
This script will count orphaned files. You can pass the  flag to also delete the files.

On wiki farms you can use the  flag to specify which wikis to process, passing in the global IDs (database names). If not provided, the script will loop through all wikis as specified in the sites table, and process any where Phonos is installed. If the sites table is not populated, the script will act only on the current wiki.

deleteOldPhonosFiles.php
This script will delete all Phonos files created before the date specified with the  option. This is useful if you for instance changed the engine, and want to force recreation of Phonos files.

Adding new a TTS engine to Phonos
Phonos was designed to be agnostic to the engine used. The only requirement for TTS engines is that they accept SSML.

Create a new subclass of  and implement the required methods. Note that  returns   by default. If there is a way to programmatically fetch (or even hard code) the list of languages, this method should be overridden in the new subclass.

If the engine doesn't produce output in MP3 format, then Lame should be used to convert the file to MP3, such that  returns only raw MP3 data. That method should also be responsible for persisting the file to disk using.
