CSS Aural Reference
CSS2 specified the number of properties for use with speech-based browsers.
CSS 2.1 retained these but, so far, no major browsers currently support these properties natively.
Furthermore, the specification actually indicates that user agents “...are not required to implement the properties of this chapter in order to conform to CSS 2.1.”
Because of this and the lack of the support, this section provides only basic information on these properties, but note that in the case of speech-enabled browsers, the properties provide improvements to specify the rate of speech, time to pause before and after words, how background sounds should be controlled, and much more.
The following shows list the CSS2 aural style properties and provide the most basic details.
