Features
Features of the voiceless labiodental fricative:
- Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence.
- Its place of articulation is labiodental which means it is articulated with the lower lips and the upper teeth.
- Its phonation type is voiceless, which means it is produced without vibrations of the vocal cords.
- It is an oral consonant, which means air is allowed to escape through the mouth.
- It is a central consonant, which means it is produced by allowing the airstream to flow over the middle of the tongue, rather than the sides.
- The airstream mechanism is pulmonic egressive, which means it is articulated by pushing air out of the lungs and through the vocal tract, rather than from the glottis or the mouth.
