Not yet, as you identify it really is about the nuance, and why people like me get paid for what we do. There are some systems that are trying to add generic emotional states using a matrix of activation vs deactivation (how energetic the delivery is) and pleasantness, to try and generate that nuance. So you can end up with emotional states like "guilt"(unpleasant with moderate deactivation) and "elation" ( pleasant with high activation), but as far as I know the application of those states are not determined through machine learning, there is still a human involvement to determine the emotional state, and then try and generate an inflection that matches it.

Narration is as much about acting as having a nice voice. We've only just begun in getting the computer voice to sound mostly human, getting it to act is another thing entirely.
