What is SSML?2015-12-02T18:48:37+01:00

SSML is a subset of VoiceXML (VXML) and thereby an XML based markup language specified by the World Wide Web Consortium (W3C).

With SSML, it is possible to augment text ranges with additional information, such as emphasis, volume, pitch or adjust the duration of the pronunciation.
A detailed set of all standard SSML tags can be found on the W3C website.
Our CereVoices do not support W3C standardized tags.
