Resumen

Speech Sound Disorder (SSD), formerly known as “dyslalia” or “phonological disorder,” is a condition that affects the phonetic and phonological aspects of language. It manifests through difficulties in the functional use of phonemes, syllables, and phonotactic organization. SSD often coexists with expressive, receptive, or mixed language disorders and is present in approximately 29% of children with language disorders. The aim of this study is to evaluate the effectiveness of the Percentage of Consonants Correct (PCC) and the Percentage of Phonological Processes (PPP) in differentiating children with SSD with and without comorbidities. This will may help on determining if any type of PPP is associated with a particular clinical group. Fifty monolingual children who speak Mexican Spanish participated in the study, which included a questionnaire assessing phonetics and phonology. The results revealed that the PCC is useful for distinguishing between SSD with and without comorbidity. The analysis of types of PPP also showed associations with certain clinical groups. In conclusion, PCC and PPP are effective in differentiating some groups of SSD with and without comorbidity, opening possibilities for various clinical applications.
