Importance of speech production for phonological awareness and word decoding: the case of children with cerebral palsy.
Poor speech output is the strongest preschool sign that a child with CP will fail at reading—treat speech first, then add phonological games.
01Research in Context
What this study did
The team watched preschoolers with cerebral palsy and typical kids do early reading games. They looked at speech clarity, rhyming, letter sounds, and later word reading.
The goal was to see which preschool skills best predict reading failure in CP.
What they found
Kids with CP scored lower on every reading warm-up skill. Poor speech production was the clearest red flag for later reading trouble.
How this fits with other research
Cologon et al. (2011) give hope: short, direct phonic lessons raised phonological awareness in Down syndrome. If it worked there, similar drills might help CP kids too.
Kocher et al. (2015) seem to disagree. They found speech clarity only mattered for spelling in deaf children, not in dyslexic hearing children. The key difference is population: their deaf group had no speech feedback loop, so clarity still shaped spelling. CP kids do hear; their issue is motor output, not sound input. Speech production still predicts their reading because it blocks practice of letter-sound play.
Robertson et al. (2017) remind us that many preschoolers with CP also have dysphagia. A child who struggles to move food safely may also struggle to move lips and tongue for speech. Check swallowing signs early; a stable oral base helps later speech and reading work.
Why it matters
You now have an early warning system. When a preschooler with CP has slurred or slow speech, start speech and phonological games right away. Pair SLP sessions with brief rhyming and first-letter games. Track progress monthly; adjust before formal reading begins.

03Original abstract
The goal of this longitudinal study was to investigate the precursors of early reading development in 52 children with cerebral palsy at kindergarten level in comparison to 65 children without disabilities. Word Decoding was measured to investigate early reading skills, while Phonological Awareness, Phonological Short-term Memory (STM), Speech Perception, Speech Production and Nonverbal Reasoning were considered reading precursors. Children with cerebral palsy lag behind on all reading precursors at the beginning of the second year of kindergarten. For the children without disabilities, early reading skills in Grade 1 were best predicted by Phonological Awareness and Phonological STM while Speech Production was the most important predictor of early reading success for the children with cerebral palsy, followed by Phonological Awareness and Speech Perception. Furthermore, for children with cerebral palsy, Speech Production appears to dominate reading development, as Speech Production measured at the beginning of the second year of kindergarten was strongly predictive of all other reading precursors measured at the end of the second year of kindergarten. The results of this study reveal that children with cerebral palsy with additional speech impairments are at risk for limited literacy development. Clinical implications are discussed.
