The voiceless uvular affricate is a type of consonantal sound, used in some spoken languages.
The tie bar may be omitted, yielding ⟨qχ⟩ in the IPA and qX in X-SAMPA.
There is also the voiceless pre-uvular affricate[1] in some languages, which is articulated slightly more front compared with the place of articulation of the prototypical voiceless uvular affricate, though not as front as the prototypical voiceless velar affricate.
The International Phonetic Alphabet does not have a separate symbol for that sound, though it can be transcribed as ⟨q̟͡χ̟⟩ or ⟨q͡χ˖⟩ (both symbols denote an advanced ⟨q͡χ⟩) or ⟨k̠͡x̠⟩ (retracted ⟨k͡x⟩).
Shaded areas denote articulations judged impossible.
