The voiceless bidental non-sibilant fricative is a type of consonantal sound used in some spoken languages. The only natural language known to use it is the Shapsug dialect of Adyghe. The constructed language Ithkuil and its offshoot Ilaksh^[1] use this sound for a geminate voiceless glottal fricative (so phonemically /hː/).^[2]

Features Edit

Features of the voiceless bidental 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 bidental, which means it is articulated with the lower and upper teeth pressed together.
• Its phonation 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 only.
• 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 lungs and diaphragm, as in most sounds.
