Electroglottography (EGG) contact quotient effectively detects vocal changes during emotional states. Negative emotions significantly increased EGG contact quotient, suggesting its viability for voice and emotion research.
Area of Science:
- Speech science
- Psychology
- Biomedical engineering
Background:
- Vocal changes during emotional situations can reveal factors in behavioral voice disorders.
- Identifying reliable vocal measures for emotion detection is crucial for targeted therapies.
Purpose of the Study:
- To assess the viability of electroglottography (EGG) contact quotient as a measure for detecting vocal alterations across different emotional states.
Main Methods:
- Electroglottography (EGG) contact quotient was measured in 18 healthy participants.
- Participants viewed images from the International Affective Picture System to elicit emotional responses.
Main Results:
- A significantly greater EGG contact quotient was observed during negative emotional conditions compared to neutral or positive conditions.
- This indicates a measurable vocal change associated with emotional valence.
Conclusions:
- Electroglottography (EGG) contact quotient shows promise as a viable measure for investigating the relationship between voice and emotion.
- This finding supports further research into using EGG for understanding emotion-induced vocal changes.
