cue

The cue, cue-before and cue-after properties specify an audio file to play before or after the browser speaks the tag. These sounds allow you to add distinguishing characteristics to tags.

For example:

h1 {cue-before: (ding.wav)}

Every time the browser finds a level 1 header in your document, it will play the ding.wav sound.

Cue is the short hand property (like font) if you give one value it plays before and after the tag. The cue-before property plays the sound before and the cue-after property plays the sound after the tag.

h1 {cue: (ding.wav)}

The cue properties work with the pause properties. If you specify both a cue and a pause for a tag, the pause is inserted between the cue sound and the tag's content.
