XSL-FO pitch Property
Definition and Usage
The pitch 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 pitch property specifies the average pitch (a frequency) of the speaking
voice.
The average pitch depends on the voice family. The average pitch for a male
voice is 120Hz, and for a female voice, it's 210Hz.
