Features

Features of the voiceless uvular 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 uvular which means it is articulated with the back of the tongue (the dorsum) against or near the uvula.
• 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.

In other languages

Several languages spoken on the northwest coast of North America have both labialized and non-labialized fricatives, including the Alsean, Salishan (Bella Coola, Klallam), Athabaskan (Chilcotin), and Wakashan languages (Nootka). Oowekyala, a Wakashan language, has labial and non-labial voiceless uvular fricatives in addition to having a voiceless pharyngeal fricative, and labial and non-labial velar fricatives.

Most variants of German realize the phoneme /x/ using this sound. It is commonly refered to as an Ach-laut after the German interjection ach
