本文综述了唐氏综合征（DS）言语产生障碍的研究，旨在为临床服务提供信息，并指导未来的研究。文献综述基于使用Medline、Google Scholar、Psychinfo和HighWire Press进行的检索，以及对检索到的文件（包括在线来源）中参考文献列表的考虑。搜索词强调与语音、发音、音韵、韵律、流畅性和可理解性相关的功能。以下结论涉及四个主要审查领域：虽然一些研究已经报道了在DS的发声异常，主要问题仍然是关于发声障碍的性质和频率。感知和声学研究的结果好坏参半，很难得出明确的结论，甚至难以确定未来研究的敏感措施。(b)说话的声音。发音和语音学研究表明，在DS的言语模式是一个延迟的发展和错误的组合没有看到在典型的发展。延迟（即，发育的）和紊乱的（即，非发育性）模式在3岁左右就很明显，尽管DS相关的异常可能出现得更早，甚至在婴儿牙牙学语时也是如此。(c)流畅和韵律。口吃和/或杂乱的发生率在DS中为10%至45%，而在一般人群中约为1%。研究还指出了韵律的显著干扰。(d)可理解性。研究一直表明，在这一领域的显着局限性，但直到最近，研究超越了简单的评级量表。
This review summarizes research on disorders of speech production in Down Syndrome (DS) for the purposes of informing clinical services and guiding future research. Review of the literature was based on searches using Medline, Google Scholar, Psychinfo, and HighWire Press, as well as consideration of reference lists in retrieved documents (including online sources). Search terms emphasized functions related to voice, articulation, phonology, prosody, fluency and intelligibility. The following conclusions pertain to four major areas of review: (a) Voice. Although a number of studies have been reported on vocal abnormalities in DS, major questions remain about the nature and frequency of the phonatory disorder. Results of perceptual and acoustic studies have been mixed, making it difficult to draw firm conclusions or even to identify sensitive measures for future study. (b) Speech sounds. Articulatory and phonological studies show that speech patterns in DS are a combination of delayed development and errors not seen in typical development. Delayed (i.e., developmental) and disordered (i.e., nondevelopmental) patterns are evident by the age of about 3 years, although DS-related abnormalities possibly appear earlier, even in infant babbling. (c) Fluency and prosody. Stuttering and/or cluttering occur in DS at rates of 10 to 45%, compared to about 1% in the general population. Research also points to significant disturbances in prosody. (d) Intelligibility. Studies consistently show marked limitations in this area but it is only recently that research goes beyond simple rating scales.
