Nasal air flow during normal speech production.

A E Thompson, T J Hixon

    The Cleft Palate Journal
    |October 1, 1979
    PubMed
    Summary
    This summary is machine-generated.

    This study on nasal airflow in 112 subjects found that older and female individuals exhibit earlier anticipatory coarticulation for nasal consonants. This indicates improved speech production with age and sex differences.

    Area of Science:

    • Speech Science
    • Phonetics
    • Acoustic Phonetics

    Background:

    • Velopharyngeal closure is crucial for distinguishing oral and nasal sounds.
    • Understanding speech development and coarticulation provides insights into phonological processes.

    Purpose of the Study:

    • To investigate nasal airflow patterns during speech in a diverse age group.
    • To determine if age and sex influence anticipatory coarticulation of nasal consonants.

    Main Methods:

    • Nasal airflow was measured in 112 participants (3-37 years old).
    • Speech samples included oral and nasal consonants and adjacent vowels.
    • Data analysis focused on airflow patterns during different speech sounds.

    Main Results:

    Related Experiment Videos

    • Nasal airflow was absent during oral sounds, indicating effective velopharyngeal closure.
    • Nasal airflow was present during nasal consonants and surrounding vowels.
    • Older and female subjects showed earlier nasal airflow, suggesting anticipatory coarticulation.

    Conclusions:

    • Velopharyngeal closure is generally airtight in normal speech.
    • Anticipatory coarticulation for nasal consonants develops with age and differs between sexes.
    • Findings contribute to understanding speech sound acquisition and production.
