Template:Infobox IPA Template:IPA notice In phonetics, denasalization is the loss of nasal airflow in a nasal sound, such as a nasal consonant or a nasal vowel.[1] 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.[2] The symbol in the Extended IPA is Template:Angbr IPA.

When one speaks with a cold, the nasal passages still function as a resonant cavity so a denasalized nasal Template:IPA does not sound like a voiced oral stop Template:IPA, and a denasalized vowel Template:IPA does not sound like an oral vowel Template:IPA.

However, there are cases of historical or allophonic denasalization that have produced oral stops. In some languages with nasal vowels, such as Paicĩ, nasal consonants may occur only before nasal vowels; before oral vowels, prenasalized stops are found. That allophonic variation is likely to be from a historical process of partial denasalization.

Similarly, several languages around Puget Sound underwent a process of denasalization about 100 years ago. Except in special speech registers, such as baby talk, the nasals Template:IPA became the voiced stops Template:IPA. It appears from historical records that there was an intermediate stage in which the stops were prenasalized stops Template:IPA or poststopped nasals Template:IPA.

Something similar has occurred with word-initial nasals in Korean; in some contexts, Template:IPA are denasalized to Template:IPA. The process is sometimes represented with the IPA Template:IPA and Template:IPA, which simply places the IPA Template:IPA denasalization diacritic on Template:IPA and Template:IPA to show the underlying phoneme.[3]
