Researchers at the University of Southern California have trained a computer algorithm to predict whether lovers will stay together based on their vocal characteristics. More details can be found in PLOS ONE.
Over the course of two years, specialists have analyzed the characteristics of the voices of 134 men and women who are in pairs and attend family psychotherapy sessions. The researchers recorded the intonation, pitch, and other vocal characteristics of people as they communicate with each other.
Then the specialists trained the algorithm to find the connection between the characteristics of the participants' voices and the final result of their relationship. This is how the algorithm learned to predict if pairs will stay together.
At the same time, psychologists also predicted the development of relationships in a couple, based on the meanings of the words spoken by the lovers, body language and some other characteristics that the algorithm did not take into account.
Psychologists' predictions were correct in 75.6% of cases, artificial intelligence predictions - in 79.3% of cases. The best results were obtained by combining the predictions of computers and psychologists (79.6%). According to the authors of the article, artificial intelligence will be able to advise couples in the future and save their relationship.
