The purpose of this experiment was to compare methods of measuring velar position during speech movements from lateral-view cineradiographic films. Specifically, correlations were calculated between measurements from a radiopaque marker sutured to the oral surface of the velum and three velar measurements that do not involve a radiopaque marker. As the correlations with the marker measurements were relatively high, it is concluded that experimenters may be free to choose any of the measurement procedures. The attachment of radiopaque markers to the velum does not appear necessary for obtaining a reliable and valid estimate of velar movements during speech.
本实验的目的是比较从侧位动态放射成像影片测量言语运动过程中软腭位置的方法。具体而言，计算了缝合在软腭口腔表面的不透射线标记物的测量值与三种不涉及不透射线标记物的软腭测量值之间的相关性。由于与标记物测量值的相关性相对较高，得出的结论是实验者可以自由选择任何一种测量程序。在言语过程中，为获得可靠且有效的软腭运动估计值，将不透射线标记物附着于软腭似乎并无必要。
