The CSS Working Group invites implementation of an updated Candidate Recommendation of CSS Speech Module. CSS (Cascading Style Sheets) is a language that describes the rendering of markup documents (e.g. HTML, XML) on various supports, such as screen, paper, speech, etc. The Speech module defines aural CSS properties that enable authors to declaratively control the rendering of documents via speech synthesis, and using optional audio cues. Note that this standard was developed in cooperation with the Voice Browser Activity.
