What is an obligatory distortion?
What is an obligatory distortion?
Obligatory distortions are those that occur when function (i.e., articulation) is normal, but the abnormal structure causes distortion of the speech sound or resonance. Examples of obli- gatory distortions are hypernasality or nasal emission that occur secondary to velopharyng- eal insufficiency (VPI).
What are obligatory errors?
a) Obligatory errors: The sounds which are produced incorrectly before the surgical repair are known as obligatory errors. It is also known as “Passive errors”. Common obligatory errors include hypernasality (too much nasal resonance), nasal emission, weak consonants, and short utterance length.
What causes nasal emission?
Nasal Emission Due to Abnormal Speech Sound Production (Misarticulation) Although nasal emission is most commonly caused by VPI or by compensatory productions secondary to VPI, nasal emission can also occur due to velopharyngeal mislearning in the absence of VPI.
How do you test for Velopharyngeal insufficiency?
How is velopharyngeal insufficiency (VPI) diagnosed?
- Endoscopy, using a medical device with lights attached that allow doctors to see inside the mouth.
- Videofluoroscopy, a type of X-ray that uses a liquid called barium to provide contrast that makes it easy for a doctor to examine the back of the mouth.
What does hypernasality mean?
Hypernasality occurs when too much sound resonates (vibrates) in the nasal cavity (nose) during speech. This type of resonance makes the patient sound as if he or she is talking through the nose.
What does Hypernasality mean?
Is hypernasality a voice disorder?
Hypernasal speech is a disorder that causes abnormal resonance in a human’s voice due to increased airflow through the nose during speech….Hypernasal speech.

How do I stop being so nasal?
Lower your voice placement in your pharyngeal and oral cavities to avoid nasal resonance. Lowering your jaw appropriately for the sounds and speaking with good range of motion with your speech articulators will help you place your voice more in the oral cavity, farther from your nasal cavity.

What causes velopharyngeal insufficiency in adults?
What causes velopharyngeal insufficiency (VPI)? The most common cause of VPI is a cleft palate, a birth defect in which there is an opening in the roof of the mouth because the palate didn’t form properly. Repair of the cleft palate may or may not also eliminate the VPI problem.
