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.
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.
