通过高速摄影、摄影声门图（PGG）和电声门图（EGG）获得的喉部振动信息进行了比较。同时声门图信号和高速电影从2个受试者产生稳定的发声。声门宽度的测量是在前后方向上沿声门沿着3个点进行的，并与其他记录对齐。PGG和胶片测量给出了基本上相同的信息，峰值声门开放和声门关闭。EGG信号似乎可靠地指示声带接触。PGG和EGG可以一起提供从高速拍摄获得的大部分信息，以及潜在地检测打开和关闭期间的水平相位差。
Information on laryngeal vibrations obtained by high-speed filming, photoglottography (PGG), and electroglottography (EGG) were compared [in humans]. Simultaneous glottographic signals and high-speed films were obtained from 2 subjects producing steady phonation. Measurements of glottal width were made at 3 points along the glottis in the anterior-posterior dimension and aligned with the other records. PGG and film measurements give essentially the same information for peak glottal opening and glottal closure. The EGG signal appears to reliably indicate vocal-fold contact. Together, PGG and EGG may provide much of the information obtained from high-speed filming as well as potentially detect horizontal phase differences during opening and closing.
