A nasal voice is a type of speaking voice characterized by speech with a "nasal" quality. It can also occur naturally because of genetic variation.
Nasal speech can be divided into hypo-nasal and hyper-nasal.

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

Hypernasal speech is a disorder that causes abnormal resonance in a human's voice due to increased airflow through the nose during speech. It is caused by an open nasal cavity resulting from an incomplete closure of the soft palate and/or velophar ...
