Acoustic rhinometry as a means to detect changes in velar position was examined in this study. Videofluoroscopic recordings were made of two normal speakers maintaining velopharyngeal open and velopharyngeal closed (silent /f/) targets. Simultaneous acoustic rhinometric recordings were made during the production of each stimulus. Determinations of changes in velar positioning during the closed samples were made from fluoroscopic recordings and compared to nasal cavity-nasopharynx changes detected by rhinometry. The excellent agreement between the measures from the two procedures (less than 1 cm) indicates that acoustic rhinometry is capable of detecting changes in velar positioning during "silent" speech. Implications for assessment and future research are discussed.
本研究对声反射鼻测量法作为检测软腭位置变化手段进行了检验。对两名正常发音者进行了视频荧光透视记录，分别记录他们保持腭咽开放和腭咽闭合（无声/f/）目标时的情况。在发出每种刺激音时同步进行声反射鼻测量记录。根据荧光透视记录确定闭合样本期间软腭位置的变化，并与通过声反射鼻测量法检测到的鼻腔-鼻咽变化进行比较。两种测量方法所得结果之间的高度一致性（小于1厘米）表明，声反射鼻测量法能够检测“无声”言语期间软腭位置的变化。文中还讨论了该研究结果对评估及未来研究的意义。
