The voiced bilabial nasal is a type of consonantal sound which has been observed to occur in about 96% of spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨m⟩, and the equivalent X-SAMPA symbol is m. The bilabial nasal occurs in English, and it is the sound represented by "m" in map and rum. Very few languages (e.g. Wyandot) are known to lack this sound. A small number of languages have been observed to lack independent nasal phonemes altogether, such as Quileute, Makah, and Central Rotokas.

Features

Features of the voiced bilabial nasal:

• Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Because the consonant is also nasal, the blocked airflow is redirected through the nose.
• Its place of articulation is bilabial, which means it is articulated with both lips.
• Its phonation is voiced, which means the vocal cords vibrate during the articulation.
• It is a nasal consonant, which means air is allowed to escape through the nose, either exclusively (nasal stops) or in addition to through the mouth.
• Because the sound is not produced with airflow over the tongue, the central–lateral dichotomy does not apply.
• Its airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.
