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.
