The W3C Voice Browser Working Group has posted the Candidate Recommendation of the Speech Synthesis Markup Language Specification. According to the abstract, the Speech Synthesis Markup Language "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."
