I don't think voice acting in itself has done that. Voice acting does however add an extra layer to the storytelling, and not everyone will be able to use it as a tool for conveying extra depth in the story, rather than something that detracts from the overall experience.
I think Mr Khan got it right, in that cinematography is to blame, or rather, the misuse of it is. Most games with cut scenes are seperated into two different parts; gameplay and videos. If those two can't be married the right way, the experience can be very disjointed or schizophrenic even. With capabilities of modern gaming hardware, telling stories through cutscenes full of emotional or bombastic moments with characters that are fully alive and "real" has become something many developers try to accomplish, with varying levels of success.
The problem is not voice acting. The problem is that too many games can't marry their gameplay with their storytelling well enough. In the "old" days, there wasn't room for making the gameplay and storytelling as different as what can be done today, and many developers seem to have moved towards thinking that cinematic games offer the best experience. And for some, that might be the case, but I personally disagree with it.
