A Sensor-enabled Digital Trier Social Stress Test in an Enterprise Context.
Annu Int Conf IEEE Eng Med Biol Soc
July 2019
Article Synopsis
- The Trier Social Stress Test (TSST) is a method to induce stress for research, traditionally done in controlled settings but adapted for remote use with employees.
- The study utilized noninvasive sensors to gather data on stress responses from twenty participants, highlighting the importance of the State Trait Anxiety Inventory (STAI) score in evaluating effects.
- The research employed machine learning techniques, achieving an F score of 0.723 with STAI as a baseline, and improved to 0.847 by using changes in STAI scores to account for subjective variations.
Comparing Manual and Machine Annotations of Emotions in Non-acted Speech.
Annu Int Conf IEEE Eng Med Biol Soc
July 2018
Psychological well-being at the workplace has increased the demand for detecting emotions with higher accuracies. Speech, one of the most non-obtrusive modes of capturing emotions at the workplace, is still in need of robust emotion annotation mechanisms for non-acted speech corpora. In this paper, we extend our experiments on our non-acted speech database in two ways.
