![]() However, we seek to establish a widely applicable approach. Either approach will satisfy our accessibility requirements. This Updating Working Draft describes two possible technical approaches for author-controlled pronunciation of HTML content, using Speech Synthesis Markup Language (SSML). This document provides normative specifications and best practices guidance so that text-to-speech (TTS) synthesis can properly pronunciation HTML content. This document is intended to become a W3C Recommendation. This document was published by the Pronunciation Task Force of Accessible Platform Architectures Working Group as a Of this technical report can be found in the A list of current W3C publications and the latest revision This section describes the status of thisĭocument at the time of its publication. ![]() We seek feedback on which approach would prove most implementable acrossĪll applications of spoken presentation of web content. Either approach described here satisfies our requirementsįor assistive technologies and will be useful to voiceĪssistants which consume and present HTML content in spoken form. Publication carefully avoid the impasse that has prevented SSML fromīecoming a native HTML technology and should, therefore, be generallyĪpplicable.
