Abstract:
This study investigates the relationship between intensity and the open quotient (OQ) and speed quotient (SQ) values of combined glottography. Simultaneous electroglottography and photoglottography were performed on 20 healthy male subjects at intensities of 55 and 65 dB. Paired t-test statistical analysis showed that the open quotient varies inversely and the speed quotient directly with the intensity. When reporting findings it is therefore necessary to state the intensity at which the results were obtained.
