title: The effect of frequency on combined glottography.
abstract: This study investigates the relationship between frequency and the open quotient (OQ) and speed quotient (SQ) values of combined glottography. Simultaneous electroglottography and photoglottography were performed on 20 healthy male subjects. Regression analysis showed that neither OQ nor SQ was dependent upon frequency. The technique is therefore still valid despite the inability to control this variable.
