title: Laryngeal configuration associated with glottography.
abstract: This report describes a method for testing and confirming the relationship of glottography to the vibratory movements of the vocal folds. According to this method, vocal fold movement is monitored by photoglottography (PGG) and electroglottography (EGG) as photographs are taken using a 80-microsecond flash provided by a laryngostroboscope. The flash is recorded as an impulse on the PGG waveform, indicating the location on the glottographic signals of the corresponding single frame photograph. We then present a test case, in which various vocal fold configurations are documented, demonstrating that the timing of glottal events can be correlated to glottographic signals by this method.
