The Articulate eLearning Challenge #223 is to show how course designers use text-to-speech in eLearning.
I used Plotagon animation to create this example, which comes with digital text-to-speech voices installed from Acapela. Plotagon also allows you to export a file with subtitles, which I imported into Storyline 360 to create the Closed-Captions.
