The purpose of the current study was to analyze an existing data set featured in Osborne (2020). More specifically, the current study aimed to identify phonological processes occurring in the speech of adolescents and adults with Down syndrome and explore subsequent impacts to speech intelligibility. Phonology coding forms from the Arizona Articulation and Phonology Scale, Fourth Revision were completed by analyzing phonetic transcriptions and audio-recordings generated during the completion of the Word Articulation subtest by participants featured in Osborne (2020). Seventeen distinct phonological processes occurred across all participant responses. Phonological process occurrence and speech intelligibility values were found to have a significant negative correlation value (r(4)= -.7883, p= .063).
