predict whether a relationship was going to get better or worse with an accuracy of just under 80%.

How they did it? The recordings were divided by acoustic features that used speech processing

techniques to track pitch and voice warble and intensity. These clips from the researchers' training

video illustrate psychological states that characterize distressed relationships.

This one, for example, shows negative effect and reactivity, behaviors that relationship experts
