Five normal speakers were used to test a novel photodetector apparatus for obtaining continuous and instantaneous recordings of velopharyngeal area during speech. The results indicate that this inexpensive instrument is able to "track" changes in velopharyngeal port size. A high correlation was found between photodetector output and velopharyngeal port size, as determined using pressure-flow measurements. Its potential use in conjunction with nasopharyngoscopic assessment and in biofeedback training is discussed.
使用了五名正常说话者来测试一种新型光电探测器设备，以获取言语过程中腭咽区域的连续和即时记录。结果表明，这种价格低廉的仪器能够“追踪”腭咽口大小的变化。通过压力-流量测量确定，光电探测器输出与腭咽口大小之间存在高度相关性。还讨论了其与鼻咽镜评估结合使用以及在生物反馈训练中的潜在用途。
