Supporting data for, 'Acoustic and Perceptual Speech Characteristics of Adults with Spastic and Athetoid Cerebral Palsy'.

This was a research study aiming at investigating the acoustic and perceptual speech characteristics in Cantonese speaking adults with Cerebral Palsy. In the study, there were 15 adults with spastic cerebral palsy, 13 adults with athetoid cerebral palsy and ten healthy controls. In the speech sampling processes, the participants were requested to complete two speech tasks. In Task 1, participants were requested to read aloud nine CVC words with corner vowels for twice. In Task 2, participants were requested to read aloud a phonetically balanced word list. The word list in Task 2 involved testing items in Hong Kong Cantonese Articulation Test and 4 disyllabic words. Acoustic analysis and perceptual analysis were used to evaluate the speech of participants. In acoustic analysis, the participants' abilities to expand vowel space, preventing collapse of vowel space, dispersing vowel formant two along the horizontal plane and vowel formant one along the vertical plane were compared. In perceptual analysis, the relative speech intelligibility scores of participants with spastic cerebral palsy, athetoid cerebral paly and healthy control in Task 1 and 2 were compared. Details of the variables involved in acoustic and perceptual analysis could be found in Readme file.

本研究旨在探究粤语方言讲者的脑瘫成年人在语音的声学及感知特征。研究中共纳入15名痉挛性脑瘫成年患者、13名手足徐动性脑瘫成年患者以及10名健康对照者。在语音采样过程中，参与者被要求完成两项语音任务。在任务1中，参与者被要求朗读九个以角元音为结尾的CVC单词，每词朗读两次。在任务2中，参与者被要求朗读一个语音平衡的词汇表。任务2中的词汇表包含香港粤语发音测试的项目以及4个双音节词。本研究采用声学分析和感知分析对参与者的语音进行评估。在声学分析中，比较了参与者扩展元音空间、防止元音空间坍塌、在水平面上分散元音共振峰二以及在垂直面上分散元音共振峰一的能力。在感知分析中，比较了任务1和任务2中痉挛性脑瘫患者、手足徐动性脑瘫患者与健康对照组的相对语音可懂度评分。声学分析和感知分析中涉及的变量细节可查阅Readme文件。
