Abstract

<abstract> <title>Abstract</title> <p>The aim of the present study was to investigate whether the glottal and filter variables of emotional expressions vary by emotion and valence expressed. Prolonged emotional vowels (<italic>n</italic> = 96) were produced by professional actors and actresses (<italic>n</italic> = 4) expressing joy, surprise, interest, sadness, fear, anger, disgust, and a neutral emotional state. Acoustic parameters and the contact quotient from the electroglottographic signal (CQ_EGG) were calculated. Statistics were calculated for the parameters. Vocal fold contact time differed significantly between the emotional expressions reflecting differences in phonation types. It was concluded that CQ_EGG may vary simultaneously and inversely with F3 and F4 in emotional expressions of positive emotions. Changes in the lower pharynx and larynx may affect the higher formant frequencies.</p> </abstract>
