Rhythmic disturbances are a hallmark of motor speech disorders, in which the motor control deficits interfere with the outward flow of speech and by extension speech understanding. As the functions of rhythm are language-specific, breakdowns in rhythm should have language-specific consequences for communication.
The goals of this paper are to (i) provide a review of the cognitive-linguistic role of rhythm in speech perception in a general sense and crosslinguistically; (ii) present new results of lexical segmentation challenges posed by different types of dysarthria in American English, and (iii) offer a framework for crosslinguistic considerations for speech rhythm disturbances in the diagnosis and treatment of communication disorders associated with motor speech disorders.
This review presents theoretical and empirical reasons for considering speech rhythm as a critical component of communication deficits in motor speech disorders, and addresses the need for crosslinguistic research to explore language-universal versus language-specific aspects of motor speech disorders.
节律紊乱是运动性言语障碍的一个标志，其中运动控制缺陷会干扰言语的外在表达，进而影响言语理解。由于节律功能具有语言特异性，节律的破坏应该会对交流产生特定语言的影响。
本文的目标是：（i）总体上并跨语言地综述节律在言语感知中的认知 - 语言作用；（ii）呈现美国英语中不同类型构音障碍所带来的词汇切分挑战的新结果；（iii）为与运动性言语障碍相关的交流障碍的诊断和治疗中言语节律紊乱的跨语言考量提供一个框架。
本综述提出了将言语节律视为运动性言语障碍中交流缺陷关键组成部分的理论和实证依据，并探讨了开展跨语言研究以探索运动性言语障碍的语言普遍性与语言特异性方面的必要性。
