Each of two adolescents with velopharyngeal closure deficits was taught to position him or herself on an endoscope attached to a television camera and to observe the velopharyngeal port during the production of syllables and other units. The videoendoscope was then used as a training apparatus, and each subject was given practice attempting to increase velopharyngeal closure while producing vowels and syllables. Videorecordings of each subject made without feedback before, during, and after the training period were played to panels of observers who were to rate closure during each utterance, and the data obtained indicated that the subjects more frequently approximated complete closure as the study progressed but improved performance was not established on an automatic level. Suggestions are made for the refinement and further investigation of videoendoscopic closure training.
两名患有腭咽闭合不全的青少年，分别被教导如何将自己置于连接电视摄像机的内窥镜上，并在发出音节和其他语音单位时观察腭咽口。然后，视频内窥镜被用作训练设备，让每个受试者在发出元音和音节时练习尝试增强腭咽闭合。在训练期之前、期间和之后，对每个受试者在无反馈情况下进行录像，并播放给观察小组，由他们对每次发声时的闭合情况进行评分。获得的数据表明，随着研究的进行，受试者更频繁地接近完全闭合，但在自动水平上并未确立改善的表现。文中针对视频内窥镜闭合训练的改进和进一步研究提出了建议。
