A voiceless bilabial nasal is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨m̥⟩, a combination of the letter for the voiced bilabial nasal and a diacritic indicating voicelessness.

Features

Features of a voiceless 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 voiceless, which means it is produced without vibrations of the vocal cords.
It is a nasal consonant, which means air is exclusively allowed to escape through the nose for nasal stops; otherwise, in addition to through the mouth.
Because the sound is not produced with airflow over the tongue, the median–lateral dichotomy does not apply.
Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most speech sounds.
