More Than Words: Inference of Socially Relevant Information From Nonverbal Vocal Cues in Speech

Abstract. This paper presents two examples of how nonverbal commu-nication can be automatically detected and interpreted in terms of social phenomena.

Furthermore, the article outlines some of the most interesting perspectives in this line of research
