The role of the soft palate in normal laryngeal functions and in the production of selected voice qualities was studied by a simultaneous velolaryngeal videoendoscopy technique. For this technique, the Olympus ENF-P flexible nasopharyngolaryngoscope was passed via one nostril to study the function of the larynx, while the Hopkins 70 degrees rhinoscopic telescope was passed via the other nostril to study the function of the soft palate and velopharyngeal closure. A Kay Elemetrics DSP Sona-Graph, model 5500, was used to analyze a complex vocal figure of five consecutive voice qualities, three of which were nasal, and two, oral. Simultaneous velolaryngeal videoendoscopy proved to be of great value for the understanding of the interaction of velar and laryngeal functions and for clarifying the mechanisms of nasal and twang qualities.
采用同步腭-喉视频内镜技术研究软腭在正常喉功能及特定嗓音特质产生中的作用。对于该技术，将奥林巴斯ENF-P型可弯曲鼻咽喉镜经一侧鼻孔插入以研究喉部功能，同时将霍普金斯70度鼻内镜经另一侧鼻孔插入以研究软腭功能及腭咽闭合情况。使用凯伊电子公司的型号为5500的DSP Sona-Graph来分析连续五种嗓音特质的复杂声谱图，其中三种为鼻音特质，两种为口音特质。同步腭-喉视频内镜对于理解腭部与喉部功能的相互作用以及阐明鼻音和鼻音化特质的机制具有重要价值。
