The role of visual feedback in the treatment of defective /s/ sounds in patients with cleft palate is described. Six patients with cleft palate who were similar in age, velopharyngeal function, and type of misarticulation were selected for this study. Treatment was provided using either visual feedback or no visual feedback. Visual feedback for tongue placement was provided by the Rion Electropalatograph (EPG). Visual feedback for frication was provided by a multi-function speech training aid (MFSTA). Improvement in /s/ sound production was assessed objectively using a method described previously (Michi et al., 1986). The results indicated that visual feedback for tongue placement and frication was especially useful in the treatment of defective /s/ sounds in patients with cleft palate who exhibited abnormal posterior tongue posturing during the production of dental or alveolar sounds.
本文描述了视觉反馈在腭裂患者/s/音缺陷治疗中的作用。本研究选取了6名年龄、腭咽功能和错音类型相似的腭裂患者。治疗采用视觉反馈或无视觉反馈。舌位的视觉反馈由理音电子腭图仪（EPG）提供。摩擦音的视觉反馈由多功能言语训练辅助工具（MFSTA）提供。使用先前描述的方法（Michi等人，1986年）客观评估/s/音产生的改善情况。结果表明，对于在发齿音或齿龈音时表现出异常舌后位姿势的腭裂患者，舌位和摩擦音的视觉反馈在/s/音缺陷治疗中特别有用。
