hypernasality

This term is primarily used in clinical settings, such as speech-language pathology and otolaryngology, to describe a specific physiological dysfunction of the velopharyngeal mechanism. It carries a neutral, diagnostic tone rather than a descriptive or judgmental one, focusing on the acoustic result of air leakage through the nasal cavity.

As a medical condition describing a quality of speech, the word is uncountable. It refers to a state or characteristic of voice production and does not occur in plural forms in standard clinical discourse.
