Abstract

To investigate whether children with velopharyngeal insufficiency (VPI) exhibit increased elevation and retraction of the tongue dorsum. Two quantitative metrics of tongue dorsum activity: Dorsum excursion Index (DEI) and Tongue Constraint Position Index (TCPI) were captured using mid-sagittal images of the tongue obtained from Ultrasound Tongue Imaging. Participants: Six children with velopharyngeal insufficiency (VPI), six children with palate (w/wo cleft lip) without velopharyngeal insufficiency (wo VPI) and ten typically developing children aged 6-15 repeated six different consonants in aCa and iCi contexts five times. A linear mixed-effect model was used to examine the response variables across three groups. Overall, DEI was not significantly higher in the VPI group than in the other two groups. Also, TCPI was not significantly lower in the cleft palate group (VPI and wo VPI). However, significant differences were detected between certain phonetic contexts in the VPI group. In addition, a significant interaction between group and consonant was found in the context of /i/. These findings suggest that the presence of VPI may not lead to a uniform increase in tongue dorsum elevation or retracted position across all speech sounds. Rather, the articulatory behaviours of children with VPI may be influenced by the specific phonetic context and individual variability.

咽发育不全儿童与发育正常儿童的舌背活动。
目的:研究患有发展性咽喉发育不全(VPI)的儿童是否会表现出舌背的抬高和回缩。舌背活动的两个定量指标:利用超声舌成像技术获得的舌中矢状面图像采集舌背偏移指数(DEI)和舌约束位置指数(TCPI)。研究对象六名患有腭咽闭合不全(VPI)的儿童、六名患有腭咽闭合不全(wo VPI)但没有腭咽闭合不全(wo VPI)的儿童和十名发育正常的 6-15 岁儿童在 aCa 和 iCi 情境下重复六种不同的辅音五次。我们采用线性混合效应模型来研究三组儿童的反应变量。总体而言,VPI 组的 DEI 并未明显高于其他两组。此外,腭裂组(VPI 和 wo VPI)的 TCPI 也没有明显降低。然而,在 VPI 组中,某些语音上下文之间存在明显差异。此外,在 /i/ 的语境中,组别与辅音之间存在明显的交互作用。这些研究结果表明,VPI 的存在可能不会导致所有语音中舌背抬高或舌尖后缩位置的一致增加。相反,VPI 儿童的发音行为可能受到特定语音环境和个体差异的影响。
