Listening 2 Faces: Improving perception of speech in noise in children with communication disorders.

项目摘要 噪音中的言语交流似乎毫不费力，因为快速的来回 过程的性质。特别是对儿童来说，沟通往往发生在 存在噪音（例如教室、操场和游乐场）。典型的儿童 发展似乎做到这一点无缝，然而，儿童与发展 自闭症谱系障碍（ASD）和听力损失（HL）等残疾， 在噪音中理解语音有明显困难，加剧了现有的社交和 沟通缺陷和负面影响的学术成果。应对这一 关键缺陷的语音理解，我们将开发一个创新的原型， 通过使用视频来增加对语音的感知灵敏度的治疗训练系统 在特定噪声类型中产生目标语音的人脸。该应用程序将 明确地训练患有ASD和HL的儿童接受间断性噪音（具有无声间隔 允许听到目标的片段），并注意来自 通过聚焦于人脸/嘴巴的视频说话。最近的证据表明 在中断的噪音中收听可以提供感知上的好处，例如重新映射， 听觉环境和学习使用声音提示。申报产品， Listening 2 Faces（L2 F）将使用自适应训练程序， 随着性能的提高而增加难度，并包括可定制的奖励， 保持兴趣，以及明确提醒注意发言者的脸（以及，在 特别是嘴）。L2 F将包括一个应用程序，通过孩子的 自己的移动终端，并可用于临床医生跟踪多个儿童，或由 照顾者跟踪每个孩子的进步。

Project Summary Speech communication in noise seems effortless because of the rapid back and forth nature of the process. For children in particular, communication often occurs in the presence of noise (e.g. classrooms, playgrounds and cafeterias). Children with typical development appear to do this seamlessly, however, children with developmental disabilities such as autism spectrum disorders (ASD) and hearing loss (HL) have significant difficulty comprehending speech in noise, exacerbating existing social and communication deficits and negatively impacting academic outcomes. To counter this key deficit in speech comprehension, we will develop a prototype of an innovative therapeutic training system to increase perceptual sensitivity to speech by using videos of human faces producing the target speech in a specific noise type. The app will explicitly train children with ASD and HL on interrupted noise (which has silent intervals that allow for fragments of the target to be heard) and to attend to information from the speaking face via videos that focus on human faces/mouths. Recent evidence indicates that listening in interrupted noise can provide perceptual benefits, such as remapping the auditory environment and learning to use acoustic cues. The proposed product, Listening 2 Faces (L2F), will use adaptive training procedures that automatically increases difficulty as performance improves, and includes customizable rewards to maintain interest, as well as explicit reminders to attend to the speaker's face (and, in particular, the mouth). L2F will include an app that administers training via the child's own mobile device, and can be used by a clinician to track multiple children, or by a caregiver to track an individual child's progress.
