Abstract
In this paper we investigate the prosody and voice quality of dominance in scenario meetings. We have found that in these
scenarios the most dominant person tends to speak with a louder-than-average voice quality and the least dominant person
with a softer-than-average voice quality. We also found that the most dominant role in the meetings is the project manager and
the least dominant the marketing expert. A set of raw and composite measures of prosody and voice quality are extracted from
the meeting data followed by a Principal Components Analysis (PCA) to identify the core factors predicting the associated social
signal or related annotation.
