Speech Synthesis Markup Language

If you need to customize the output of SpeechSynthesizer further, you could specify its input the form of a standard XML-based language known as Speech Synthesis Markup Language (SSML). SSML enables you to customize pronunciation, volume, pitch, prosody (rhythm and intonation), and more. It is a W3C Recommendation published at http://w3.org/TR/speech-synthesis.

To use SSML, you simply pass an appropriate SSML string to SpeechSynthesizer’s SynthesizeSsmlToStreamAsync method instead of SynthesizeTextToStreamAsync. Here’s an example of SSML content that demonstrates some of its features:
