The present paper discusses the key deficits present in the development of children with Down syndrome, which determine the course of speech therapy. The reduction of intellectual capacity, the impairment of perception development, irregularities in the anatomy of speech organs and incorrect socio-emotional development, all of them constitute the limitations which result in the delays in language acquisition by children especially in their early years. Nevertheless, the retarded language acquisition does not mean that the child would not master the language at all, but rather it means that this process is much slower than the pace of life.
