The observation of articulatory movements, particularly of velar movements, is of considerable theoretical and practical interest in evaluating the velopharyngeal function of the cleft palate patient. A new electromagnetic device is presented for tracking the movements of the velum and the tongue simultaneously in correlation with the posterior pharyngeal wall and the hard palate in the midsagittal plane. An inductive measuring principle is used; a miniature transmitting coil is placed at the lower margin of the velum, another coil is used for recording the position of the posterior pharyngeal wall as well as the surface of the hard palate and the movements of the tongue dorsum. The measuring principle is described and the movements of the velum during speech production are demonstrated in cleft palate patients with different speech results.
观察发音运动，尤其是腭咽运动，对于评估腭裂患者的腭咽功能具有重要的理论和实践意义。本文介绍了一种新型电磁装置，用于在矢状面内同时追踪软腭和舌与咽后壁及硬腭相关的运动。该装置采用感应测量原理；一个微型发射线圈置于软腭下缘，另一个线圈用于记录咽后壁、硬腭表面以及舌背的位置和运动。文中描述了测量原理，并展示了不同语音结果的腭裂患者在言语产生过程中软腭的运动情况。
