Abstract
Down Syndrome (DS) is a genetic disorder characterized by an extra chromosome on pair 21. Compared to neurotypical individuals, people with DS exhibit developmental delays, including language development. One of the most affected components is the phonetic-phonological level. There is a lack of research on this issue in Spanish-speaking children with DS, highlighting the need for further studies. This research aims to describe the production of rising and falling diphthongs in children with DS aged between 5.0 and 9.11 years from the regions of Valparaíso, Metropolitana, and Bío Bío. Data from the FONDECYT Project No. 11150658 were used to this end, comprising a sample of 35 children who were administered the Prueba de Fonología en Español (Spanish Phonology Test). The words were transcribed, and those containing diphthongs were analyzed. The results indicate that children with DS show delayed phonetic-phonological acquisition compared to the typically developing population. No age-related effect was found in the average correct production of diphthongs. Additionally, performance was better for rising than for falling diphthongs. Errors were primarily observed as first-segment omissions in rising diphthongs and second-segment omissions in falling diphthongs.
