Twilio Changelog
Additions and changes to the Twilio platform
Studio now supports SSML tags when using Amazon Polly voices in Say/Play and Gather Input On Call widgets.
To enable SSML, select a default Polly voice from the Text-to-Speech Settings in Twilio Console or select one from the Voice dropdown menu on the Studio widget.
Add the SSML tags you wish to use directly in the Text to Say field.
Learn more in the Say/Play widget docs.
