Abstract

Down syndrome is an underdevelopment physical and mental condition in children caused by chromosomal development abnormalities. Signs that show from down syndrome may vary from the invisible, slightly visible to a typical sign of down syndrome. The most typical sign of children with Down syndrome is the children’s underdevelopment of physical and mental condition (Olds, London, &Ladewing, 1996). Down syndrome sufferers are very easily recognizable by the presence of a prominent physical appearance where the head is relatively smaller than normal head (microcephaly) with (anteroposterior) the head flattened. On the face usually can be seen from the flat and low bridge nose, the mouth is smaller and the tongue slightly larger and sometimes protrudes out (macroglossia). The eyes slant upwards and have an extra fold of skin on the upper eyelid (epicanthic folds). Down Syndrome children also have sensory difficulties, speaking barriers, and verbal development. This study aims to identify the speech impairment disorder in Down Syndrome children. The research method used is mix methods. The data source is conversation which produced by Down Syndrome children's aged 8-10 years old. The results showed that DS children had an indication of disruption (1) voice production, i.e. noise production to communicate verbally, (2) disruption in speech sounds, i.e. disruption in phoneme production on certain vowels and consonants, and (3) fluency and prosody, i.e. pitch production, duration and formants
