Pressure-flow data are often used to provide information about the adequacy of velopharyngeal valving for speech. However, there is limited information available concerning simultaneous pressure-flow measurements for oral and nasal sound segments produced by normal speakers. This study provides normative pressure, flow, and velopharyngeal orifice area measurements for selected oral and nasal sound segments produced by 10 male and 10 female adult speakers. An aerodynamic categorization scheme of velopharyngeal function, including one typical category and three atypical categories (open, closed, and mixed) is proposed.
压力-流量数据常被用于提供有关腭咽瓣在言语中功能是否充足的信息。然而，关于正常说话者发出的口腔音段和鼻音段同时进行压力-流量测量的可用信息有限。本研究提供了10名成年男性和10名成年女性发出的特定口腔音段和鼻音段的标准压力、流量及腭咽口面积测量值。提出了一种腭咽功能的空气动力学分类方案，包括一个典型类别和三个非典型类别（开放、闭合和混合）。
