A nasal voice is a type of speaking voice characterized by speech with a "nasal" quality to it. It can also occur naturally because of genetic variation.

Nasal speech can be divided into hypo-nasal or hyper-nasal.

Hyponasal speech[edit]

Hyponasal speech is a lack of appropriate nasal airflow during speech, such as when a person has nasal congestion.

Some causes of hyponasal speech are adenoid hypertrophy, allergic rhinitis, deviated septum, sinusitis, and turbinate hypertrophy.

Hypernasal speech[edit]

Hypernasal speech is inappropriate increased airflow through the nose during speech, especially with plosives and fricatives (syllables that begin with a consonant).

Examples of hypernasal speech include cleft palate and velopharyngeal insufficiency.
