The voiceless velar affricate is a type of consonantal sound, used in some spokenlanguages. The symbols in the International Phonetic Alphabet that represents this sound are ⟨k͡x⟩ and ⟨k͜x⟩, and the equivalent X-SAMPA symbol is k_x. The tie bar may be omitted, yielding ⟨kx⟩ in the IPA and kx in X-SAMPA.
Some languages have the voiceless pre-velar affricate,[1] which is articulated slightly more front compared with the place of articulation of the prototypical voiceless velar affricate, though not as front as the prototypical voiceless palatal affricate - see that article for more information.
Conversely, some languages have the voiceless post-velar affricate,[2] which is articulated slightly behind the place of articulation of the prototypical voiceless velar affricate, though not as back as the prototypical voiceless uvular affricate - see that article for more information.
Features
Features of the voiceless velar affricate:
Its manner of articulation is affricate, which means it is produced by first stopping the airflow entirely, then allowing air flow through a constricted channel at the place of articulation, causing turbulence.
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 an oral consonant, which means air is allowed to escape through the mouth only.
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.
^Instead of "pre-velar", it can be called "advanced velar", "fronted velar", "front-velar", "palato-velar", "post-palatal", "retracted palatal" or "backed palatal".
^Instead of "post-velar", it can be called "retracted velar", "backed velar", "pre-uvular", "advanced uvular" or "fronted uvular".
