Investigating the phonetic expression of successful motivation
Jana Voße, Petra Wagner · ExLing Conferences · 2018
The present study provides a comprehensive acoustic phonetic analysis of motivational speech by collecting, annotating, and processing 50 minutes of speech data representing less and more successful degrees of motivation. The analysis shows significant differences regarding acoustic phonetic features such as $f_0$ (fundamental frequency: median, range, variation), intensity (median, range), and speaking rate. We observe inconsistent results for the variation of intensity, pointing to the necessity of a more fine-grained analysis of this specific feature. Overall, this study provides initial support for the existence of a distinct motivational speaking style.
