These sounds are called “vowels,” “nasal consonants” and “low pressure consonants.” In English, these include m, n, ng, h, l, w, y, r and all the vowel sounds. A child with an unrepaired cleft palate can produce these sounds. A closed soft palate with airflow (shaded) through the mouth.

How do you assess hypernasality and Hyponasality?
Using voiced (resonating) sounds, assess for the following:
- Hypernasality—excessive nasal resonance on vowels and voiced oral consonants.
- Hyponasality—too little or absent resonance on nasal consonants and adjacent vowels, especially /i/ and /u/.
What sounds does Velopharyngeal insufficiency affect?
When a child has VPI, the pressure consonants may sound weak or muffled. As air escapes through the nose, it may sound like puffs, squeaks or snorts.
What is the difference between hypernasality and Hyponasality?
Hypernasality—occurs when there is sound energy in the nasal cavity during production of voiced, oral sounds. Hyponasality—occurs when there is not enough nasal resonance on nasal sounds due to a blockage in the nasopharynx or nasal cavity.
What sounds does hypernasality affect?
Hypernasal speech is the sound of speech that results from too much air escaping through the nose while talking. There are certain letters and sounds that should not have air escaping through the nose during speech. Examples of these are vowels, or letters like “s”, “b”, and “k”.
