# 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.
