hyponasality

This term is primarily used in clinical settings, such as speech-language pathology and otolaryngology, to describe a specific acoustic quality of voice. It refers to the perceived "stuffy" sound that occurs when the nasal cavity is blocked or the velopharyngeal port is closed, preventing air from escaping through the nose during the production of nasal consonants like /m/ and /n/.

Because it describes a physiological state or a medical condition, it is treated as an uncountable noun. It is the direct opposite of hypernasality, where too much air escapes through the nose, creating a "nasal" tone. In a diagnostic context, it is often associated with conditions like rhinitis, nasal polyps, or severe common colds.
