小脑疾病影响许多熟练的动作，包括说话的动作。共济失调构音障碍，言语障碍，通常伴随小脑疾病，研究了声学方法。研究人员记录了对照组和共济失调构音障碍患者在执行一系列口语任务时的情况，包括持续的元音发音、音节重复、单音节单词生成（可理解性测试）、句子背诵和对话。来自语音样本的声学数据证实了时间失调是语音障碍的主要组成部分的假设。数据还显示，障碍的性质随说话任务的不同而不同。这一结果与对小脑疾病患者其他运动系统的观察结果一致，可能是损伤分离的证据。对特定任务的选择措施和小脑在说话调节中的作用提出了建议。
Cerebellar disease affects a number of skilled movements, including those in speech. Ataxic dysarthria, the speech disorder that typically accompanies cerebellar disease, was studied by acoustic methods. Control subjects and subjects with ataxic dysarthria were recorded while performing a number of speaking tasks, including sustained vowel phonation, syllable repetition, monosyllabic word production (intelligibility test), sentence recitation, and conversation. Acoustic data derived from the speech samples confirmed the hypothesis that temporal dysregulation is a primary component of the speech disorder. The data also show that the nature of the disorder varies with the speaking task. This result agrees with observations on other motor systems in subjects with cerebellar disease and may be evidence of a dissociation of impairments. Suggestions are offered on the selection of measures for a given task and on the role of the cerebellum in the regulation of speaking.
