Relationship Between Intelligibility in Context Scale and Cleft-Related Speech Sound Errors in 3-Year-Olds With Nonsyndromic Cleft (Lip and) Palate

The presence of anterior oral errors and passive errors reduced speech intelligibility across different communication partners. Non-oral errors did not show as strong an impact, although specific subtypes like glottal articulation did reduce ICS scores. These findings suggest the importance of individualized treatment strategies, with increased attention to specific subtypes of cleft-related speech sound errors.
