    Summary
    This summary is machine-generated.

    This study investigated velopharyngeal activity in esophageal speakers using acoustic measurements. Results show their velopharyngeal mechanism is slower but still functional for speech.

    Area of Science:

    • Speech-language pathology
    • Acoustic analysis
    • Physiology of speech

    Background:

    • Esophageal speech is a method for alaryngeal speech.
    • Velopharyngeal function is crucial for speech intelligibility.
    • Understanding velopharyngeal activity in esophageal speakers is important for rehabilitation.

    Purpose of the Study:

    • To indirectly investigate velopharyngeal activity in esophageal speakers.
    • To assess the oral-nasal acoustic ratio during esophageal speech.
    • To determine the functional capacity of the velopharyngeal mechanism in this population.

    Main Methods:

    • Utilized TONAR II instrumentation to measure the oral-nasal acoustic ratio.
    • Studied eight proficient esophageal speakers using injection insufflation.

  • Subjects read standardized passages with varying nasal consonant content.

    • Main Results:

    • Esophageal speakers demonstrated a slower velopharyngeal mechanism.
    • The velopharyngeal mechanism was found to be functional despite reduced speed.
    • Acoustic analysis indicated effective oral-nasal separation during speech.

    Conclusions:

    • The velopharyngeal mechanism in skilled esophageal speakers operates functionally.
    • Slower velopharyngeal activity is characteristic of this speaker group.
    • Further research can explore therapeutic interventions to optimize velopharyngeal function.
