Laughs, sighs, and screams: Understanding when, why, and how we vocalise Dr D.A. Sauter, Department of Psychology, University of Amsterdam People often make noises like laughing, screaming, and sighing. In this project, researchers will establish when, how, and why we make such sounds. The project will analyse video and audio recordings made in everyday life by people from different cultures, as well as the vocalisations of deaf individuals and babies. The results will be useful for understanding voice pathologies in clinical populations, as well as shining a light on common everyday behaviours.
