Summary

Children with speech sound disorders exhibit similar consonant cluster realization patterns to typically developing peers. Analysis reveals systematic relationships between adult and child phonology, reducible to four key constraints.

Area of Science:

  • Linguistics
  • Speech-Language Pathology
  • Developmental Psychology

Background:

  • Children with functional speech disorders often exhibit difficulties with complex sound structures like consonant clusters.
  • Understanding the phonological processes in children with speech disorders is crucial for effective intervention.
  • Generative phonology provides a framework for analyzing children's sound systems.

Purpose of the Study:

  • To compare consonant cluster realization patterns in children with speech disorders to those of typically developing children.
  • To analyze the relationship between adult phonological representations and children's underlying and phonetic representations.
  • To identify constraints governing children's cluster production.

Main Methods:

  • Analysis of consonant cluster realizations in 47 children (ages 3;4 to 6;8) with functional speech disorders.

Related Experiment Videos

  • Application of a two-level generative phonology model.
  • Utilizing feature geometry and underspecification theory to examine phonological representations.

    • Main Results:

    • Consonant cluster realization patterns in children with speech disorders are comparable to those reported for normal acquisition.
    • Systematic and principled relationships exist between adult and child phonological representations (underlying and phonetic).
    • Observed diversity in cluster realizations can be explained by four constraints on representations.

    Conclusions:

    • Children with functional speech disorders follow similar phonological development pathways for consonant clusters as their peers.
    • Phonological theories like feature geometry and underspecification effectively explain children's cluster production.
    • A limited set of constraints governs the complexities of children's consonant cluster realization.
