The articulation of children with Down's syndrome (trisomie 21, T21) in comparison to a group of age-matched normal probands was investigated in a clinical study, using digital sonagraphics (recording of frequency, amplitude and time of the speech signal), with peripheral factors taken into consideration. The T21-Group (n = 10) revealed a higher variability as well as a longer articulation of the test word "Tasse" than the Control Group (n = 10). There was no clear-cut dependence of speed and quality of articulation on all of the peripheral factors evaluated (Angle Class, overbite, oral motor ability, hearing disorder, logopedics, Castillo-Morales stimulating plate treatment). The results of our investigation show differing patterns of articulation in T21 children compared with normal probands, using a reproducible method. A clear-cut influence of various influencing peripheral factors as reported in the literature could not be found for the T21-Group. Thus, central factors seem to have a great impact on articulation in T21 patients.
在一项临床研究中，运用数字超声成像技术（记录语音信号的频率、振幅和时间），并考虑周边因素，对唐氏综合征（21三体综合征，T21）患儿与一组年龄匹配的正常对照者的发音进行了调查。与对照组（n = 10）相比，T21组（n = 10）在测试单词“Tasse”的发音上表现出更高的变异性和更长的发音时间。发音的速度和质量与所评估的所有周边因素（安氏分类、覆合、口腔运动能力、听力障碍、言语治疗、卡斯蒂略 - 莫拉莱斯刺激板治疗）之间没有明确的相关性。我们的调查结果表明，使用可重复的方法，T21患儿与正常对照者的发音模式不同。对于T21组，未发现文献中报道的各种周边影响因素的明显影响。因此，中枢因素似乎对T21患者的发音有很大影响。
