Yes! UI Builder allows “Hear it now” functionality as part of the rich text editor.

We have integrated our popular Hear It now functionality from the Zammo portal to allow builders to test how their multi-turn content will sound on voice experiences.

In order to trigger it, you will need to add a Speech element to the Send Response (or Ask a Question) block.

Currently, the Hear It Now in UI Builder only supports the Azure Voice. We will be adding the Google Assistant and Amazon Alexa voices in a future release.
