本文介绍了收购一个新的数据库构音障碍的语音对齐声学和发音数据。该数据库目前包括7名脑瘫或肌萎缩侧索硬化症所致言语障碍患者的数据，以及年龄和性别匹配的对照组。每一个有语言障碍的人都由语言病理学家对语言运动功能进行标准化评估。声学数据由一个头戴式麦克风和一个定向麦克风获得。发音数据是通过电磁关节造影术获得的，它允许在讲话过程中测量舌头和其他发音器官，并通过双目视频序列的3D重建。刺激是从各种来源，包括TIMIT数据库，识别语音对比列表，和语音清晰度的评估。本文还分析了构音障碍言语与非构音障碍言语在音素长度、发音错误等方面的区别。
This paper describes the acquisition of a new database of dysarthric speech in terms of aligned acoustics and articulatory data. This database currently includes data from seven individuals with speech impediments caused by cerebral palsy or amyotrophic lateral sclerosis and age- and gender-matched control subjects. Each of the individuals with speech impediments are given standardized assessments of speech-motor function by a speech-language pathologist. Acoustic data is obtained by one head-mounted and one directional microphone. Articulatory data is obtained by electromagnetic articulography, which allows the measurement of the tongue and other articulators during speech, and by 3D reconstruction from binocular video sequences. The stimuli are obtained from a variety of sources including the TIMIT database, lists of identified phonetic contrasts, and assessments of speech intelligibility. This paper also includes some analysis as to how dysarthric speech differs from non-dysarthric speech according to features such as length of phonemes, and pronunciation errors.
