Abstract：
The current study aimed to assess the effectiveness of incorporating ultrasound visual biofeedback (UVB) into a treatment programme addressing persistent speech sound disorders linked to cleft palate in children who have been unresponsive to traditional therapy approaches. Materials and Methods. A single-subject multiple baseline experiment was conducted with five children aged 6:5-13:5 over a period of 16 therapy sessions. Treatment focused on providing cues from real-time ultrasound images to assist children in modifying their tongue movements. Probe data were collected before, mid, and post-treatment to assess target consonant accuracy for 50 untreated words. The results of the statistical analysis suggested participants showed a significant increase in percent target consonant accuracy as a result of intervention using UVB. Although most of the participants exhibited progress in generalising learned phonemes to untreated words, some did not show improvement in gaining generalisation from treated phonemic contexts to those untreated ones. When traditional methods fail to yield significant progress, incorporating ultrasound biofeedback into the treatment programme emerges as a viable option to enhance sound accuracy in children with persistent speech sound disorders resulting from cleft palate.
摘要：
目前的研究旨在评估将超声视觉生物反馈（UVB）纳入治疗计划的有效性，以解决对传统治疗方法无反应的儿童与c裂有关的持续语音障碍。材料和方法。在16个疗程的时间内，对5名6：5-13：5的儿童进行了单受试者多基线实验。治疗的重点是从实时超声图像中提供提示，以帮助儿童修改舌头运动。之前收集了探针数据，mid,和后处理，以评估50个未处理单词的目标辅音准确性。统计分析的结果表明，由于使用UVB进行干预，参与者的目标辅音准确度百分比显着提高。尽管大多数参与者在将学习的音素概括为未经处理的单词方面取得了进展，有些人在从经治疗的音素语境到未经治疗的音素语境的推广方面没有表现出改善。当传统方法无法取得重大进展时，将超声生物反馈纳入治疗方案是一种可行的选择，可以提高因left裂引起的持续语音障碍儿童的声音准确性。
