Thanks for your feedback! We felt that this storyline / length was best in order to showcase the two different actor's artificial voices and build up to the actual cry.
As you've mentioned, we do work with real actors to create our TTS and take misuse of their (artificial) voices very seriously. Because they sound so lifelike, we've made the decision not to allow public access/personal use at this time.
Lastly, your assessment is spot on regarding standard vs custom voices. Lots of interest for both!
