💬 New research is changing the way we understand children’s speech sound disorders — and it’s really encouraging for families.
A new study, The Articulatory Basis of Phonological Error Patterns in Childhood Speech Sound Disorders, has found evidence for something speech pathologists trained and experienced in orofacial myology see every day:
👉 Many speech sound errors aren’t just “phonological” or rule-based — they’re linked to real differences in how a child’s jaw, lips, and tongue move.
The study looked at 48 preschool children with moderate–severe speech sound disorders and found:
🔹 Difficulties like cluster reduction, final consonant deletion, stopping, fronting, and gliding were strongly connected to underlying speech motor control challenges.
🔹 These children often had reduced control of the jaw, lips, and tongue — the exact muscles and movements needed to make clear speech.
🔹 Interestingly, gliding (“wabbit” for “rabbit”) was less related to motor difficulty and may be a compensatory stage.
🔹 Speech errors weren’t just “mix-ups” — they often reflected the child’s developing motor system.
✨ Why this matters:
This research supports approaches used by speech pathologists with training in orofacial myology, who blend phonological learning with motor-based strategies to strengthen, coordinate, and refine speech movements.
For parents, this means:
✔ Your child isn’t “lazy” or “not trying.”
✔ Many speech errors reflect real developmental differences.
✔ Motor-informed therapy can target underlying causes, not just symptoms.

Speech acquisition involves complex coordination of articulatory structures, primarily the jaw, lips, and tongue. Typically developing children acquire speech sounds in a hierarchical sequence governed by progressive neuromotor maturation. However, ...
