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.
本报告描述了一种用于测试和确认声门图与声带振动运动之间关系的方法。根据该方法，在使用喉频闪仪提供的80微秒闪光灯拍摄照片时，通过光电声门图（PGG）和电子声门图（EGG）监测声带运动。该闪光灯在PGG波形上记录为一个脉冲，表明相应单帧照片在声门图信号上的位置。然后我们给出一个测试案例，其中记录了各种声带形态，证明通过这种方法声门事件的时间可以与声门图信号相关联。
