DESCRIPTION (provided by applicant): Ultrasound technology has been shown to be a new tool in the treatment of speech sound disorders. It helps diagnose problems and can provide visual feedback to help children correct errors they make in producing the sounds of their language. Recent advances have made this imaging technique more accessible to clinicians, both in terms of price and of ease of use. The present proposal will facilitate the translation of the research into clinical practice so that a wide range of clients can begin to benefit from these technological advances. One part of the project will test the usefulness of looking at the types of tongue shapes used by children with speech problems. Research has found that some children use tongue shapes that are relatively adult-like but incorrect, while others use an "undifferentiated" shape-that is, a shape that shows limited accommodation to different sounds. These undifferentiated tongue shapes may indicate that a different kind of therapy is called for. We will test two kinds of therapy on misarticulating children. We expect to find that knowing whether a child uses undifferentiated shapes or not (as seen with ultrasound imaging) will allow the selection of the better treatment program. A particularly difficult sound is that of /r/, as i "right", "try" and "car." Ultrasound imaging can help children see what their tongue should be doing to get a perceptually correct sound. We will further test elements of this feedback procedure so that we can provide evidence-based guidance for implementing ultrasound treatment in clinics everywhere. Further support for the approach will come from magnetic resonance imaging (MRI) of the tongue in children with good and poor /r/ pronunciation. We will validate ultrasound imaging of the tongue against MRI images, and we will also collect MRI images that can be used to model appropriate tongue shapes for children. While our MRI images from adults have proven useful in helping children pick an appropriate tongue shape for /r/, we predict that MRI images of children will be even more informative. Improving the articulation of this common sound will help thousands of children.

描述（由申请人提供）：超声技术已被证明是治疗语音障碍的新工具。它可以帮助诊断问题，并提供视觉反馈，帮助儿童纠正他们在产生语言声音时所犯的错误。最近的进展使这种成像技术更容易为临床医生所接受，无论是在价格上还是在易用性上。目前的建议将有助于将研究转化为临床实践，以便广泛的客户可以开始从中受益 技术进步。 该项目的一部分将测试观察有语言问题的儿童使用的舌形类型的有用性。研究发现，有些孩子使用的舌头形状与成人相似，但并不正确，而另一些孩子使用的是“未分化”的形状，也就是说，这种形状对不同声音的适应能力有限。这些未分化的舌形可能表明需要不同类型的治疗。我们将测试两种治疗发音错误儿童的方法。我们希望发现，了解儿童是否使用未分化的形状（如超声成像所见）将允许选择更好的治疗方案。 一个特别困难的声音是/r/，因为i“right”，“try”和“car”。“超声波成像可以帮助孩子们看到他们的舌头应该做什么，以获得感知正确的声音。我们将进一步测试这种反馈程序的要素，以便我们能够为各地诊所实施超声治疗提供循证指南。对这种方法的进一步支持将来自于/r/发音好和差的儿童舌头的磁共振成像（MRI）。我们将根据MRI图像验证舌头的超声成像，我们还将收集可用于为儿童建立适当舌头形状模型的MRI图像。虽然我们的成人MRI图像已被证明有助于帮助儿童为/r/选择合适的舌形，但我们预测儿童的MRI图像将提供更多信息。改善这种常见声音的发音将帮助成千上万的儿童。
