To study the associations between the articulation of the Finnish /r/ sound and dentofacial and pharyngeal lateral cephalometric morphology and speech physiology, 18 (12 females, 6 males) young adult cleft patients' /r/ sound was analysed auditorily by 3 speech experts. Laryngeal resistance (LARE), the smallest nasal cross-sectional area (NASA), nasal resistance (NASAR) and velopharyngeal orifice area (VEPA) were measured with pressure flow technique, and 31 points were identified from the lateral cephalograms to landmark the skeletal structure, pharyngeal airway diameters, and position of the hyoid bone. The present results showed no significant differences in lateral cephalometric skeletal, nasopharyngeal, oropharyngeal or hypopharyngeal morphology between subjects with and without /r/-sound distortion. There were no significant correlations either between /r/ distortions and NASA, NASAR or VEPA. An anteriorly positioned hyoid bone was significantly associated with decreased LARE and /r/ distortion. LARE was significantly lower in subjects with /r/ distortion.
为研究芬兰语/r/音的发音与牙颌面及咽侧位头颅形态学和言语生理学之间的关联，3名言语专家对18名（12名女性，6名男性）年轻成年腭裂患者的/r/音进行了听觉分析。采用压力流技术测量喉阻力（LARE）、最小鼻横截面积（NASA）、鼻阻力（NASAR）和腭咽孔面积（VEPA），并从侧位头颅X线片中确定31个点，以标记骨骼结构、咽气道直径和舌骨位置。目前的结果显示，有/r/音失真和无/r/音失真的受试者在侧位头颅骨骼、鼻咽、口咽或下咽形态上没有显著差异。/r/音失真与NASA、NASAR或VEPA之间也没有显著相关性。舌骨位置靠前与LARE降低和/r/音失真显著相关。有/r/音失真的受试者的LARE显著较低。
