Sounds amazing! Just to add a usecase - for many people, creating a decent voiceover is one of the big sticking points for producing youtube videos or educational courses. If I could write a script, and have software generate a decent enough voiceover, it would be amazing.

It's not even necessary to copy anyone's voice, as long as there's a selection of the most comprehensible and human-sounding ones.

Then, you could even automatically generate slideshow presentation from a few illustrations and headlines, and that would make "rendering" articles into videos very fast and easy. I'm sure a lot of people would pay for such service.

By the way, recently I've encountered Deep Voice 2, a similar research project by baidu:

Results are very impressive.
