Speakers with autism spectrum disorders (ASD) show difficulties in suprasegmental aspects of speech production, or prosody, those aspects of speech that accompany words and sentences and create what is commonly called "tone of voice." However, little is known about the perception of prosody, or about the specific aspects of prosodic production that result in the perception of "oddness." The present study examined the perception and production of a range of specific prosodic elements in an experimental protocol involving natural speech among speakers with ASD between 14 and 21 years of age, in comparison with a typical control group. Results revealed ceiling effects limiting interpretation of findings for some aspects of prosody. However, there were significant between-group differences in aspects of stress perception and production. The implications of these findings for understanding prosodic deficits is speakers with autism spectrum disorders, and for future research in this area, are discussed.
患有自闭症谱系障碍（ASD）的说话者在言语产生的超音段方面，即韵律方面存在困难，韵律是伴随单词和句子并创造出通常所说的“语调”的言语方面。然而，对于韵律的感知，或者导致“怪异”感知的韵律产生的具体方面，人们知之甚少。本研究在一个实验方案中，对14至21岁患有ASD的说话者与典型对照组之间自然言语中的一系列特定韵律元素的感知和产生进行了研究。结果显示，天花板效应限制了对某些韵律方面研究结果的解释。然而，在重音感知和产生方面，两组之间存在显著差异。本文讨论了这些发现对于理解自闭症谱系障碍患者韵律缺陷的意义以及该领域未来研究的意义。
