Review Questions and Correct Answers
Airway interruption method ✅an indirect method of measuring subglottal pressure,
which estimates lung pressure from the intraoral pressure.
Amplitude perturbation quotient ✅a measure comparable to the jitter measure of
relative amplitude perturbation, in that it averages the amplitude over 11 cycles.
Contact quotient ✅the ratio of the period during which the vocal folds are in contact to
the entire glottal cycle. Sometimes referred to as the closed quotient.
Dichrotic (creaky) Phonation ✅common in glottal fry and also some abnormal
phonatory modes. If, within a single cycle, the vocal folds were to close, bounce open,
and then rapidly close again before finally opening to complete the cycle, one would
obtain two moments of acoustic excitation. The perception of this double excitation
typically is described as dichrotic, or creaky.
Electroglottography EGG ✅a technique that provides a waveform that has been shown
to correspond to the relative contact of the vocal folds during vibration.
Falsetto register/loft ✅occupies the frequencies above modal register. This register is
most easily recognized in the male voice at a very high pitch. Also called loft register.
Frequency perturbation quotient/ RAP ✅the average difference in periods between
each three adjacent cycles is divided by the average period. In this way, the RAP
largely removes any slow shift in frequency that may occur during normal sustained
phonation. Also called the frequency perturbation quotient.
Genomics ✅the study of genomes, the total genetic information available in a cell.
Glottal efficiency ✅ratio of aerodynamic power to acoustic power at the level of the
glottis.
Glottal fry/Pulse Register ✅a mode of phonation in which the F0 is quite low,
approximately 35 to 50 Hz, in both men and women. Also called glottal fry.
Glottography ✅refers to the analysis of vibratory movements of the vocal folds during
phonation using any one or a combination of measures including photoglottography,
and inverse filtering that does not include direct visualization of the vocal folds.
High-speed laryngeal imaging/video ✅a technique of imaging the vibrating vocal folds
that, unlike stroboscopy, images the actual true rate of vibratory movement.
