Call for Review: Speech Synthesis Markup Language (SSML) Version 1.1 Proposed Recommendation

Author(s) and publish date


The Voice Browser Working Group has published a Proposed Recommendation of Speech Synthesis Markup Language (SSML) Version 1.1. The Speech Synthesis Markup Language Specification is designed to provide a rich, XML-based markup language for assisting the generation of synthetic speech in Web and other applications. The essential role of the markup language is to provide authors of synthesizable content a standard way to control aspects of speech such as pronunciation, volume, pitch, rate, etc. across different synthesis-capable platforms. SSML 1.1 improves SSML 1.0 support for a broader set of natural (human) languages. Known implementations are documented in the Implementation Report, along with the associated test suite. Comments are welcome through 23 March. Learn more about the Voice Browser Activity.
