  • Title: Vocal responses to emotional picture viewing.
    Author: van Mersbergen M, Delany M.
    Journal: Logoped Phoniatr Vocol; 2014 Oct; 39(3):99-107. PubMed ID: 23570409.
    Abstract:
    Vocal changes in emotional situations may identify contributing factors in behavioral voice disorders and direct more efficient therapies. Finding appropriate measures of voicing that detect emotional conditions is a first step in this line of investigation. The purpose of this study was to determine whether electroglottography (EGG) contact quotient is a viable measure to detect vocal changes in different emotion states. Vocal responses in 18 vocally healthy participants were measured using EGG contact quotient during picture viewing from the International Affective Picture System. Results demonstrated that in negative emotional conditions participants employed significantly greater EGG contact quotient than in neutral or positive conditions. EGG contact quotient appears to be a viable measure to investigate voice and emotion.
