From Speech to Personality: Mapping Voice Quality and Intonation into Personality Differences

From a cognitive point of view, personality perception corresponds to capturing individual dierences and can be thought of as positioning the people around us in an ideal personality space. The more similar the personality of two individuals the closer their position in the space. This work shows that the mutual position of two individuals in the personality space can be inferred from prosodic features. The experiments, based on ordinal regression techniques, have been performed over a corpus of 640 speech samples comprising 322 individuals assessed in terms of personality traits by 11 human judges, which is the largest database of this type in the literature. The results show that the mutual position of two individuals can be predicted with up to 80% accuracy.
