Definitions of the nine vibratory characteristics used to compare the downsampled tokens to the original 16000-fps recordings.

Clinical Feature	Definition
Mucosal Wave Magnitude	Maximum difference between the lower and upper vocal fold margins during the closing phase (i.e. vertical phase difference or divergence angle)
Mucosal Wave Extent	Extent of lateral propagation of the mucosa during the closing phase
Amplitude Asymmetry	Amplitude difference between left-right vocal-fold vibration
Phase Asymmetry	Phase difference between left-right vocal-fold vibration
Aperiodicity	Variation of the period of the glottal vibratory cycle
Glottal Edge	Smoothness and shape of the vibrating vocal-fold edges
Contact	Realization of contact of the vocal folds during vibration
Loss of Contact	Loss of contact of the vocal folds during vibration
Mucus Bridges Breaking	Release of mucus strand bridging the glottis
