Summary

This study analyzed speech errors in Cantonese-speaking children with repaired cleft palate. Findings revealed significant variability and unique language-specific errors, like initial consonant deletion.

Area of Science:

  • Speech-Language Pathology
  • Pediatric Audiology
  • Craniofacial Anomalies

Background:

  • Cleft palate repair can impact speech sound production.
  • Understanding phonological patterns in children with repaired cleft palate is crucial for targeted interventions.
  • Cantonese, a tonal language, presents unique linguistic features that may influence speech development post-surgery.

Purpose of the Study:

  • To investigate speech sound errors in Cantonese-speaking children with repaired cleft palate.
  • To identify patterns of phonological errors and their variability within and across subjects.
  • To compare findings with existing research on cleft palate speech in other languages.

Main Methods:

  • Speech samples were collected from seven Cantonese-speaking children (aged 3;2-10;2) with repaired cleft palate using two word lists.

  • Perceptual judgments were used for detailed analysis of error patterns.
  • Confusion matrices were created for each subject to quantify error frequencies.

    • Main Results:

    • High variability in speech sound errors was observed both within individual subjects and across the group.
    • Some results aligned with findings in other languages, such as posterior placement for alveolar targets.
    • Distinct language-specific errors were identified, including initial consonant deletion in Cantonese.

    Conclusions:

    • Speech sound production in Cantonese-speaking children with repaired cleft palate is characterized by considerable variability.
    • The presence of language-specific errors highlights the need for culturally and linguistically tailored speech therapy.
    • Further research is warranted to explore the underlying causes and develop effective intervention strategies.
