INTELLIGIBILITY ASSESSMENT IN DYSARTHRIA

描述：构音障碍是几种神经系统疾病的常见结果， 包括帕金森氏症、中风、小脑病变、多发性 硬化症和创伤性脑损伤。节律障碍通常会导致 语音可理解性，但它们也会影响口语的其他方面 语言，包括音质、韵律和副语言特征。这些 还没有在大量具有 构音障碍。该项目使用多任务协议，同时具有感知和 声学测量用于检查清晰度、声音质量、韵律和 获得性构音障碍儿童和成人的副语言方面。几个 新开发的分析将用于为 构建语言障碍和神经损伤的概况。包括在内 将是第一次系统地复制导致 构音障碍的现代分类。有关构音障碍的数据将是 结合神经中的语言发育和正常成人语言的数据 基于听觉内部模型的语音产生网络模型 以及语音的发音表示法。

DESCRIPTION: Dysarthria is a frequent result of several neurological disorders, including Parkinson disease, stroke, cerebellar pathologies, multiple sclerosis, and traumatic brain injury. Dysarthrias often lead to decreased speech intelligibility, but they also affect other dimensions of spoken language, including voice quality, prosody, and paralinguistic features. These have not been studied collectively in large numbers of individuals with dysarthria. This project uses a multiple-task protocol with both perceptual and acoustic measures to examine intelligibility, voice quality, prosody, and paralinguistic aspects in children and adults with acquired dysarthria. Several newly developed analyses will be used to provide quantitative data toward the construction of profiles of speech impairment and neurologic lesion. Included will be the first systematic replication of the original work that led to the contemporary classification of the dysarthrias. The data on dysarthria will be integrated with data on speech development and normal adult speech in a neural network model of speech production that is based on internal models of auditory and articulatory representations of speech.
