The voiceless velar affricate is a type of consonantal sound, used in some spoken languages. 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.
