It is pretty good on the audio/voice side. I will say my son figured it out it was not real pretty quickly with a different example. These types of media are pretty formulaic so they lend themselves to computer generation. I can see news reports being automated with tech like this. Those people all sound the same already and have almost no personality.

When you listen to several of these you start to pick up on repetitive patterns though. But I pick up on those with real people as well. Its kinda interesting.
