In phonetics, denasalization is the loss of nasal airflow in a nasal sound. That may be due to speech pathology but also occurs when the sinuses are blocked from a common cold, when it is called a nasal voice, which is not a linguistic term. Acoustically, it is the "absence of the expected nasal resonance." The symbol in the Extended IPA for partial denasalization is ⟨◌͊⟩.
