XSL-FO speech-rate Property
Definition and Usage
The speech-rate 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 speech-rate property specifies how fast the text should be read - the
speaking rate.
