Abstract : Oral communication plays a key role in social and professional relations. Face-to-face interview, appreciated in managerial and commercial areas, remains the richest human interpersonal interaction thanks to innate and joint use of verbal and non-verbal social cues. That is the reason why at Zero to One Technology, we develop a diagnostic and pedagogical tool : the Comscope. With simulated and recorded interview practicing, then by extracting and analyzing automatically social cues, it provides measurement of the quality of the interaction in order to improve it. The research for this thesis is principally directed towards the analysis of gaze signal. In order to do so, we created new estimators for head-pose, gaze direction and time of focus of attention on the interlocutor. All the estimators are based on facial landmarks detection and iris location extraction. By use of low-resolution video recording devices in visible light, they must work together in real time and in uncontrolled environment. We also created a way of assessing automatically the technical quality of an interview by classification. We used the features extracted from gaze (eye movements and fixations, time of attention), speech (speaking time estimation and transcript of exchange : lexicology analysis, interview labelling), and their multimodal and crossed analysis.
