Agree. It's even easy to do manually in audacity with recorded tracks. There are probably some ML innovations here (maybe isolating the voice signal from the background in a way that lets you label the phase info sufficiently to correlate it) but the main innovation that I can see is packaging it in a way that's useful in this context.
