I tried a dummy scripts with 2 different actors as I figured out how the software works.

I was impressed by the AI text to Voice as it has inflection and pauses and it sounds "almost" natural.

I was NOT impressed with the video though.

The first try had a very creepy feel to it as the lips didn't sync well and the actor was so stiff. The weird blinking seemed unnatural too.

The second try was even worse. The lips moved like an animal eating grass.

I'm not sure if you can watch but here's the link to the 2nd try https://login.deepword.co/video/b47y6a6qcfl4yh8c98

I also found the clothing to be inappropriate, mainly because it was ill-fitting and didn't align with what I expected.

Finally, if the actors could start off with a smile, it would make a big difference.

I'd suggest that the developer invest in more actors, and have the clothing category be something like "office" with classic, well-fitting office attire (suits), "smart casual" with work-appropriate or Sunday-best clothes, "casual" with on-trend clothes, "formal" for parties and perhaps only a few actors have the "medical" attire.

I also suggest that they permit body movement so that it is more natural.

Finally, for the actors, it's good to see a range of ethnicities and different body shapes/sizes. I'd like to see this expand though, along with more age range.

I also didn't find any female actors that I would believe to be CEOs or Executives.

But, more than anything, they need to work on making the face react more naturally.
