Wow, I didn't know about this project but the samples are very good. Clearly they need some post processing (I'm guessing he used ted talks that may explain the slight microphone tone) then they will be even more realistic.

I wonder if he used in-sample text or cherry picked the best (he mentioned they were some of the better ones).

I will definitely check that out.

Update:listening long sentences some of them are clearly used audiobook library. But some of the short sentences seems to be from ted talks. Update2: double wow, I just listened tom and weaver without checking their names.They definitely sound a lot like real actors themselves as I immediately recognized the actors.
