Oral-nasal differential pressures are derived measures that incorporate both active (e.g., articulatory) and passive (e.g., nasal structure) components. This study was designed to examine integrated oral-nasal differential pressures in speakers with different levels of velopharyngeal closure. Integrated oral-nasal differential pressure data were obtained from 20 noncleft adults with normal speech and 166 speakers with repaired palatal clefts. Velopharyngeal competency for the cleft subjects, as determined by aerodynamic assessment, ranged from adequate to grossly incompetent. Results of the data analysis indicate that integrated pressures are not maintained at a consistent level across all groups. This lack of consistency across all degrees of velopharyngeal opening may reflect the flexibility, as well as structural limitations, of a speech pressure regulating system.
口鼻压差是一种综合测量指标，它包含主动成分（如发音动作）和被动成分（如鼻腔结构）。本研究旨在检查不同腭咽闭合程度的说话者的综合口鼻压差。综合口鼻压差数据来自20名言语正常的非腭裂成年人和166名腭裂修复后的说话者。通过气动评估确定，腭裂受试者的腭咽功能从足够到严重不足不等。数据分析结果表明，所有组的综合压力并非保持在一致水平。在所有腭咽开口程度上缺乏一致性，可能反映了言语压力调节系统的灵活性以及结构限制。
