The approach in the article is roughly equivalent to having someone listen to you speak and then repeating back in their own voice so you can attempt to copy their accent. Certainly nice to have available on demand without needing to coordinate schedules with another human.
A good accent coach would be able to do much better by identifying exactly how you're pronouncing things differently, telling you what you should be doing in your mouth to change that, and giving you targeted exercises to practice.
Presumably a model that predicts the position of various articulators at every timestamp in a recording could be useful for something similar.
