What is the current "state of the art" in future audio sample prediction, given recent developments in "image inpainting" using deep learning?
These Images are FAKE !!!
There is absolutely no way, no algorithm, no nothing that exist that can tell you whether the eyes of a girl are blue or black by just looking at her lips !!!
You can guess, something, good or bad, based on your prior training and the probabilities based on that, but that's just a guess.
The fact that the synthesized images look so natural is the key to deceive people into thinking that the algorithm correctly predicts the impossible to fix missing information.
No algorithms can tell whether she had a tattoo in her screwed part of the image !!!
What the algorithm is doing is that you feed it with correct information in many many other training images, from different angles, different illuminations etc. Then the algorithm will try at best (and may succeed just as painting artist would do) to replace the missing pixels from those of the available set... And if she had a tattoo in the mean time; forget about it !
Same is for audio...
