Resonance in speech production
- Coupling between nasal and oral cavities
- Coupling for sustained vowels, fricatives, nasals
- Coupling during running speech
- Development of VP function
- Measuring VP function
- Disorders of VP function
- Treatment of hypernasality
Objectives
- Describe the status of the velopharyngeal port for sustained vowels, fricatives, and nasals and identify the cavities through which air flows for each type of sound.
- Briefly explain the development of velopharyngeal function from infancy to three years of age.
- Explain why adenoidectomy could result in velopharyngeal dysfunction.
- Describe how VP function can be observed and measured using direct visualization, X-ray imaging, aeromechanical techniques, and acoustic techniques.
- Explain the effect of velopharyngeal dysfunction on speech.
- Identify functional and organic causes for VP dysfunction.
