XSL-FO volume Property
Definition and Usage
The volume property is used only in Aural Stylesheets.
The aural rendering of a document combines sounds and voices to go through
the content of a document. Aural presentation occurs often by converting the
document to plain text and then feeding this to a screen reader.
Situations and markets for listening to information could be:
- for blind people
- in the car
- help users learning to read
The volume property specifies the volume of the speaking voice. User agents
should allow the volume to be changed by the listener.
