Prosody and Voice Quality of Vocal Social Signals: The Case of Dominance in Scenario Meetings
3 11th Annual Conference of the International Speech Communication Association 2010 (INTERSPEECH 2010) volume 1, Makuhari, Japan, ISCA, ISCA, 9/2010
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.
