Investigating Stress-Related Speech Features Effect of Perceived Stress, Mindfulness and Personality on Stress-Related Speech Features

Abstract

What is the role of perceived stress, mindfulness and personality in predicting stress through acoustic features? This study aims to explore these three psychological dimensions by asking 86 participants to record their speech over 10 days using their smartphones. Based on their relation with stress, the study hypothesizes that perceived stress and mindfulness would predict stress-related speech features whilst personality dimensions would explain the variance in features. Linear mixed effect found both perceived stress and mindfulness to predict increase in fundamental frequency, while certain personality dimensions found increase in F0 and Shimmer. The findings suggest the possibility of using acoustic features as a measure of stress.
