Recognition of Personality Traits from Human Spoken Conversations

We are interested in understanding human personality and its manifestations in human interactions. The automatic analysis of such personality traits in natural conversation is quite complex due to the user-profiled corpora acquisition, annotation task and multidimensional modeling. While in the experimental psychology research this topic has been addressed extensively, speech and language scientists have recently engaged in limited experiments. In this paper we describe an automated system for speaker-independent personality prediction in the context of human-human spoken conversations. The evaluation of such system is carried out on the PersIA human-human spoken dialog corpus annotated with user self-assessments of the Big-Five personality traits. The personality predictor has been trained on paralinguistic features and its evaluation on five personality traits shows encouraging results for the conscientiousness and extroversion labels.
