Velopharyngeal closure is one of the conditions for normal pronunciation, and when we pronounce normally, the soft palate and pharyngeal wall form a closure, separating the oropharyngeal cavity from the nasopharyngeal cavity for normal, clear speech.
Palopharyngeal insufficiency refers to the inability of the velopharyngeal mouth to separate the nasal cavity from the oral cavity during pronunciation, which is mainly manifested by excessive nasal sounds (abnormal nasal resonance), nasal leakage, and specific compensatory articulation, resulting in decreased articulation clarity. In children with velopharyngeal insufficiency, his nasal voice is heavier, his voice is rougher, muffled and heavy, his pronunciation position is lower, and his pronunciation is not clear.
When swallowing, food may regurgitate into the nasal passages, causing coughing, ear tightness, and hearing loss. If there is such a child, we need to be evaluated and examined by a voice trainer, and even with the help of an endoscope to see if the child's soft palate is enough to close the oropharyngeal and nasopharyngeal cavities and form a closure when pronouncing words.
Children with velopharyngeal insufficiency can be able to pronounce normally and clearly through surgery or voice training. For specific ways to do this, please consult a professional physician offline.
