We investigate the influence of audiovisual features on the perception of speaking style and performance of politicians, utilizing a large publicly available dataset of German parliament recordings. We conduct a human perception experiment involving eye-tracker data to evaluate human ratings as well as behavior in two separate conditions, i.e. audiovisual and video only. The ratings are evaluated on a five dimensional scale comprising measures of insecurity, monotony, expressiveness, persuasiveness, and overall performance. Further, they are statistically analyzed and put into context in a multimodal feature analysis, involving measures of prosody, voice quality and motion energy. The analysis reveals several statistically significant features, such as pause timing, voice quality measures and motion energy, that highly positively or negatively correlate with certain human ratings of speaking style. Additionally, we compare the gaze behavior of the human subjects to evaluate saliency regions in the multimodal and visual only conditions. The eye-tracking analysis reveals significant changes in the gaze behavior of the human subjects; participants reduce their focus of attention in the audiovisual condition mainly to the region of the face of the politician and scan the upper body, including hands and arms, in the video only condition.
