Hypernasal speech

Hypernasal speech is a speech disorder characterized by an abnormal resonance in a person's voice due to increased airflow through the nose during speech. It is often associated with conditions that affect the velopharyngeal mechanism, which helps to regulate the airflow between the oral and nasal cavities.

Causes

Hypernasal speech can be caused by a variety of conditions, including cleft palate, adenoidectomy, neurological disorders, and velopharyngeal insufficiency. It can also be a symptom of certain genetic disorders, such as 22q11.2 deletion syndrome.

Diagnosis

Diagnosis of hypernasal speech typically involves a comprehensive speech evaluation, which may include acoustic analysis, nasometry, and videofluoroscopy. These tests can help to determine the severity of the hypernasality and identify any underlying causes.

Treatment

Treatment for hypernasal speech often involves speech therapy, which can help to improve speech resonance and articulation. In some cases, surgery may be recommended to correct any physical abnormalities that are contributing to the hypernasality.
