The development of the language of people with Down syndrome (DS) occurs more easily, it is not their communicative performance. Neurological, auditory and other factors involved in the process of language acquisition and development. Another major problem in Down syndrome and work memory deficit. Such deficits appear to be linked to the dysfunction of a network of cerebral connections including as connections in the frontal region. It is difficult to study children's difficulties in working memory tasks and the result of their poor performance in verbal processing tasks, or if there are other issues involved. The purpose of this study was to investigate a relationship between difficulties of working memory and expressive language in people with Down Syndrome. Habitat 15 with SD companies with 07 and 26 years that are part of an extension project linked to a Higher Education Institution of Paraíba. All the items under speech and hearing assessment were submitted to an expressive vocabulary evaluation by the image naming test: ABFW - Vocabulary; evaluation of working memory through nonword repetition tests and content based on Hage and Grivol (2009). Then, an inferential statistical analysis was performed, and the use of non-parametric Mann-Whitney correlation test and to verify the degree of relationship variables or chi-square test. The results do not have an expressive vocabulary test, which showed an average of 64.60% of usual verbal assignments (DVU), 1.75% non-design design (ND) and 33.63% substitution (PS). No performance by semantic category had the best performance in category forms and cores and the worst was in the local category. In the tests of working memory and average of results of 31.36 points in the test of nonwords, and in the test of digits of direct order the average of 5.57 points. The performance in the non-words test was influenced by the extension of the word, that is, the higher the number of syllables, the worse the performance of the individuals. A correlation between the non-words test and direct digits as means of DVU and PS (ABFW) were significant. That is, the better the results in the non-words and work order tests, the better the performance without expressive vocabulary testing. There was no significant relationship between variables such as age, schooling and literacy with tests of memory and expressive vocabulary.
