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

项目摘要 由于快速的来回，在噪音中进行语音交流似乎不费力 过程的性质。特别是对儿童来说，沟通经常发生在 存在噪音(如教室、操场和自助餐厅)。典型的儿童 发展似乎无缝地做到了这一点，然而，患有发展性疾病的儿童 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很大困难，加剧了现有的社会和 沟通障碍，并对学业成绩产生负面影响。来对抗这一点 针对语音理解的关键缺陷，我们将开发一个创新的原型 一种利用视频提高语音知觉敏感度的治疗训练系统 在特定噪声类型中产生目标语音的人脸。这款应用程序将 明确训练患有ASD和HL的儿童对中断噪声(有静默间隔)的认识 允许听到目标的片段)，并注意来自 通过专注于人脸/嘴巴的视频说话。最近的证据表明 在被打断的噪音中倾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学提示。提议的产品， 倾听2张脸(L2F)，将使用自适应训练程序，自动 随着性能的提高增加了难度，并包括可定制的奖励，以 保持兴趣，并明确提醒注意演讲者的脸(以及，在 特别是嘴巴)。L2F将包括一款应用程序，通过孩子的 自己的移动设备，可由临床医生用于跟踪多个儿童，或由 照顾者跟踪单个孩子的进展情况。

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.
