Voiceless bilabial nasal
The 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. The equivalent X-SAMPA symbol is m_0.

Features
Features of the 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 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.
- The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and diaphragm, as in most sounds.

Features
Features of the Voiceless labiodental nasal:
- 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.
- Its place of articulation is labiodental, which means it is articulated with the lower lip and the upper teeth.
- Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
- It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
- The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and diaphragm, as in most sounds.

Les phonèmes nasals sont généralement réalisés comme des consonnes sonores, mais il peut y avoir des réalisations sourdes (rhumatisme prononcé [-sm̥]). Ces réalisations sourdes se rencontrent en particulier en finale absolue, après consonne sourde
