- W4387446537 abstract "There is a growing need for public speaking skills in both professional and private life. With this background, our research project’s long-term aims are to develop tools that can analyse public speeches and provide helpful feedback. The impact of audio and visual characteristics on the automatic analysis of speech quality has been widely explored in the existing literature. However, only a few studies have focused on textual features. In response to this shortcoming, this paper investigates the importance of textual content for the automatic analysis of public speaking. We created an open-source Python library of textual features and integrated them as inputs of simple machine-learning models for automatic public-speaking analysis, and persuasiveness prediction, in particular. The best result (accuracy of ) is obtained using a logistic regression. We then evaluated the impact of these features on persuasiveness prediction using both correlation analysis and Explainable AI methods. This evaluation was conducted on the French data set 3MT_French, including student performances in the Ma Thèse en 180 Secondes competition." @default.
