DTBook XML to DAISY 3 Conversion Guide

The DAISY Pipeline App is a multi-format converter, and it includes a script that transforms a DTBook XML file into the DAISY 3 format book with or without audio in text-to-speech voices. Note that a Microsoft Word document can be converted to a DTBook XML file using Save as DAISY available free of cost from the DAISY Consortium website.

If you have any book/document in DTBook XML format follow the steps given below to convert it to DAISY 3.

1. 1. Start the Pipeline App and wait for the Pipeline engine to start (this could take 15-30 seconds).
   2. Click on File in the menu at the top and then click on Settings.
   3. In the TTS engines tab make sure your preferred TTS engine such as Azure is connected. You can check the article Using Azure and Google TTS in DAISY Pipeline for more information.
   4. In the Voices tab of the Settings window, make sure to select voices that support languages contained in the DTBook file you are going to convert. Generally you will select one voice unless the XML file has multiple languages, in which case you should be selecting one voice for each language. Click on Save and Close button to save your preferences.
   5. Now in the Pipeline app main screen, click on New Job in File menu or click the + shaped button.
