Speech modification by a deaf child through dynamic orometric modeling and feedback.

S G Fletcher, A Hasegawa

    The Journal of Speech and Hearing Disorders
    |May 1, 1983
    PubMed
    Summary

    This study shows a deaf child learned speech sounds using visual lip cues. Targeted visual feedback improved her production of vowels and consonants.

    Area of Science:

    • Speech-language pathology
    • Audiology
    • Linguistics

    Background:

    • Characterizing speech production in deaf children is crucial for developing effective interventions.
    • Understanding pre-intervention articulatory strategies informs targeted therapy design.

    Observation:

    • A 3 1/2-year-old deaf girl primarily used visual lip and jaw movements for speech sound differentiation.
    • Her speech production lacked reliance on tongue positioning cues.

    Findings:

    • Instrumental visual feedback effectively taught the production of /i/ and /a/ vowels.
    • Linguapalatal contact patterns for /t/ were successfully integrated with vowel production.
    • The child rapidly acquired target articulatory gestures, including positional and timing aspects.

    Implications:

    • Visual articulatory modeling and feedback programs can significantly improve speech production in deaf children.
    • This approach offers a promising avenue for enhancing phoneme acquisition and speech intelligibility.
    • Findings support the integration of technology-aided speech therapy for pediatric hearing loss.
