XSL-FO speech-rate Property

Back

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.
