Testing the concurrent and predictive relations among articulation accuracy, speech perception, and phoneme awareness

Area of Science:

• Child language acquisition
• Speech-language pathology
• Developmental psychology

Background:

• Articulation accuracy, speech perception, and phoneme awareness are key components of early language development.
• Understanding the interrelations between these skills is crucial for identifying potential speech sound disorder risks.
• Previous research has explored these links, but specific phoneme-based relationships require further investigation.

Purpose of the Study:

• To examine the concurrent and longitudinal relationships among articulation accuracy, speech perception, and phoneme awareness in young children.
• To investigate phoneme-specific effects, using the target phoneme /r/ and control phoneme /m/.
• To test a model where articulation accuracy influences phonological representations, impacting sound perception and manipulation.

Main Methods:

• A sample of 97 typically developing children (ages 48-66 months) participated.
• 46 children were assessed twice (ages 4 and 5 years) for longitudinal analysis.
• Children completed tasks assessing articulation, perception, and awareness for /r/ and /m/ in word-initial positions.

Main Results:

• Phoneme-specific relationships were found between articulation, awareness, and perception.
• /r/ articulation accuracy predicted /r/ speech perception and phoneme awareness, even after controlling for covariates.
• Longitudinal analyses confirmed these predictive relationships.

Conclusions:

• Children's articulation accuracy plays a significant role in their phonological development.
• Accurate speech production appears to influence the development of phonological representations, affecting sound perception and manipulation.
• These findings support a model where motor-speech skills impact broader phonological abilities in early childhood.
