Washington: Words can deceive, but tone of voice cannot as a new study has suggested that voice tone analyses of therapy sessions can accurately predict marital success.
A new computer algorithm can predict whether you and your spouse will have an improved or worsened relationship based on the tone of voice that you use when speaking to each other with nearly 79 percent accuracy.
In fact, the algorithm did a better job of predicting marital success of couples with serious marital issues than descriptions of the therapy sessions provided by relationship experts.
Researchers recorded hundreds of conversations from over one hundred couples taken during marriage therapy sessions over two years, and then tracked their marital status for five years.
"What you say is not the only thing that matters; it's very important how you say it. Our study confirms that it holds for a couple's relationship as well," researcher Md Nasir said.
Psychological practitioners and researchers have long known that the way that partners talk about and discuss problems has important implications for the health of their relationships.
However, the lack of efficient and reliable tools for measuring the important elements in those conversations has been a major impediment in their widespread clinical use.
These findings represent a major step forward in making objective measurement of behavior practical and feasible for couple therapists, Brian Baucom said.
The study appears in Proceedings of Interspeech.
