Use of Electroglottograph (EGG) to Find a Relationship between Pitch, Emotion and Personality

摘要

To ensure a more effective and applicable emotion recognition system with the use of an electroglottography (EGG) device, we investigated the relationship between pitch (an average frequency value obtained in terms of vibration around the neck), and the emotion felt, and if personality plays a role in the identification of emotions. Some of the motivations of this work include lie detection and paediatric emotional health evaluation. In this study, data obtained from EGG and DISC personality assessment of 25 participants were analysed. We found that EGG can actually serve the function to identify emotions between neutral, happy and sad. Through the use of mixed model ANOVA, the results of happy, neutral and sad are statistically different at p = 0.01. As to whether personality affects emotion expression, a significant main effect for personality was not found and only a weak interaction between pitch and personality was reported. Thus contrary to the hypothesis that extroverts and introverts would convey emotions with different intensity and accuracy, there is no noticeable effect of personality on the emotion recognition system.
