Mobile phones pervade our everyday life like no other technology, but the effects they have on one-to-one conversations are still relatively unknown. This paper focuses on how mobile phones influence negotiations, i.e., on discussions where two parties try to reach an agreement starting from opposing preferences. The experiments involve 60 pairs of...

This article presents experiments on automatic detection of laughter and fillers, two of the most important nonverbal behavioral cues observed in spoken conversations. The proposed approach is fully automatic and segments audio recordings captured with mobile phones into four types of interval: laughter, filler, speech and silence. The segmentation...

The INTERSPEECH 2013 Computational Paralinguistics Challenge provides for the first time a unified test-bed for Social Signals such as laughter in speech. It further introduces conflict in group discussions as a new task and deals with autism and its manifestations in speech. Finally, emotion is revisited as task, albeit with a broader range of ove...

This article proposes experiments on the automatic recognition of personality traits and conflict handling style based on nonverbal communication. The tests are performed over the SSPNet-Nokia Corpus, a collection of 60 mobile phone calls (120 subjects in total) based on the Winter Survival Task. Nonverbal behavioral cues are extracted from speech...

Lexical and prosodic accommodation have been observed in many studies as contributing importantly to these dimensions of social interaction. However, while previous works have conside...

This article proposes experiments on decision making based on the "Winter Survival Task", one of the scenarios most commonly applied in behavioral and psychological studies. The goal of the Task is to identify, out of a predefined list of 12 items, those that are most likely to increase the chances of survival after the crash of a plane in a polar...

Nonverbal behaviour influences to a significant extent our perception of others, especially during the earliest stages of an interaction. This article considers the phenomenon in two zero acquaintance scenarios: the first is the attribution of personality traits to speakers we listen to for the first time, the second is the social attractiveness of...
