Speech samples of 20 adolescents and adults with Down's syndrome were analysed and compared with speech samples from 20 normal toddlers. Consonant, vowel and diphthong productions were studied. Error rate, sounds in error, nature of the errors and phonetic characteristics of the errors of both groups were compared. It was found that the similarities between productions of persons with Down's syndrome and the utterances of normal children by far outnumbered the differences. The results of this study strongly support the contention of Lenneberg (1967) that the disordered articulation in subjects with Down's syndrome reflect a delay in speech development.
对20名患有唐氏综合征的青少年和成年人的语音样本进行了分析，并与20名正常幼儿的语音样本进行了比较。研究了辅音、元音和双元音的发音情况。比较了两组的错误率、错误发音、错误性质以及错误的语音特征。结果发现，唐氏综合征患者的发音与正常儿童话语之间的相似之处远远多于差异。这项研究的结果有力地支持了伦内伯格（1967年）的观点，即唐氏综合征患者的发音障碍反映了语言发展的延迟。
