Growing evidence suggests that speech intervention using visual biofeedback may benefit people for whom visual skills are stronger than auditory skills (for example, the hearing-impaired population), especially when the target articulation is hard to describe or see. Diagnostic ultrasound can be used to image the tongue and has recently become more compact and affordable leading to renewed interest in it as a practical, non-invasive visual biofeedback tool. In this study, we evaluate its effectiveness in treating children with persistent speech sound disorders that have been unresponsive to traditional therapy approaches. A case series of seven different children (aged 6-11) with persistent speech sound disorders were evaluated. For each child, high-speed ultrasound (121 fps), audio and lip video recordings were made while probing each child's specific errors at five different time points (before, during and after intervention). After intervention, all the children made significant progress on targeted segments, evidenced by both perceptual measures and changes in tongue-shape.
越来越多的证据表明，使用视觉生物反馈的言语干预可能会使视觉技能强于听觉技能的人群（例如听力受损人群）受益，尤其是当目标发音难以描述或观察时。诊断超声可用于对舌头进行成像，并且最近变得更加紧凑且价格合理，这使得人们对其作为一种实用的、非侵入性的视觉生物反馈工具重新产生了兴趣。在本研究中，我们评估了其在治疗对传统治疗方法无反应的持续性语音障碍儿童方面的有效性。对七名患有持续性语音障碍的不同儿童（年龄在6至11岁之间）进行了病例系列评估。对于每个孩子，在五个不同时间点（干预前、干预期间和干预后）探测每个孩子的特定错误时，进行了高速超声（121帧/秒）、音频和唇部视频记录。干预后，所有孩子在目标音段上都取得了显著进展，这在感知测量和舌形变化中都得到了证明。
