A new, intensity-based method of measuring syllable duration was used to assess syllabic timing in 75 patients with dysarthria of predominantly traumatic and cerebro-vascular origin and in 30 normal subjects. The applied speech tasks included repetitions of sentences containing chains of plosive-vowel-syllables. The logarithm of the duration of the syllable carrying sentence accent proved to be particularly highly correlated with perceived speech rate. Among the potential sources of temporal variability, segmental influences and the influence of sentence stress were examined. Further, the between-sentence variation of syllable duration was assessed. The resulting measures of variability were correlated with the severity of dysarthric impairment. A strengthening of normal effects was found in the consonant-related variation, whereas intrinsic vowel effects and the influence of sentence stress were largely reduced. These results are discussed from the viewpoint of timing theories in speech and limb motor control. They are considered to provide a valuable background against which the speech impairments of specific neurologic groups can be tested.
一种基于强度的新的音节时长测量方法被用于评估75名主要由创伤性和脑血管性病因导致构音障碍的患者以及30名正常受试者的音节计时。所应用的言语任务包括重复包含爆破音-元音-音节链的句子。结果表明，承载句子重音的音节时长的对数与感知到的言语速率特别高度相关。在时间变异性的潜在来源中，研究了音段影响和句子重音的影响。此外，还评估了句子间音节时长的变化。由此产生的变异性测量值与构音障碍损害的严重程度相关。在与辅音相关的变异中发现正常效应增强，而内在元音效应和句子重音的影响在很大程度上减弱。从言语和肢体运动控制的计时理论角度对这些结果进行了讨论。它们被认为提供了一个有价值的背景，据此可以测试特定神经学组别的言语障碍。
