Automatic Tagging and Recognition of Stance

From activities as simple as scheduling a meeting to those as complex as balancing a national budget, people take stances, evaluate proposals by others, and, eventually, reach a decision. These stance-taking processes are often carried out verbally. The aim of this study is to investigate the automatic recognition of attitudes in conversations involving negotiation and argumentation. The main interest is in understanding how people express their opinions and how that process influences the decisions that are reached. In particular, this study compares how stances are expressed through the combination of pitch, speech rate, and vowel space expansion, and how the acoustic features extracted from the conversational speech data can be utilized to predict decision-making outcomes based on the stances expressed.
