The way you sound affects your mood
Covert digital manipulation of vocal emotion alter speakers’ emotional states in a congruent direction

2016/1/13

Researchers have created a digital audio platform that can modify the emotional tone of people's voices while they are talking, to make them sound happier, sadder or more fearful. New results show that while listening to their altered voices, participants' emotional state change in accordance with the new emotion. The study was conducted by researchers at the Science and Technology of Music and Sound Lab (STMS), (IRCAM/CNRS/UPMC) and the LEAD Lab (CNRS/University of Burgundy) in France, Lund University in Sweden, and Waseda University and RCAST(the University of Tokyo) in Japan.

The paper, entitled "Covert digital manipulation of vocal emotion alter speakers’emotional states in a congruent direction", has been published in Proceedings of the National Academy of Scienceson Jan. 11, 2016.
