Kh is a digraph found in some writing systems, based on the Latin alphabet. In transcriptions of Indo-Aryan languages, it represents the aspirated voiceless velar plosive (/kʰ/). For scores of other languages, it represents the voiceless velar fricative (/x/), for example in transcriptions of the letter ḥāʼ (خ) in standard Arabic, standard Persian, and Urdu. As the transcription of the letter Ḥet (ח) in Sephardic Hebrew, it represents the voiceless pharyngeal fricative. It is also used to to transcribe the Hebrew letter Kaf (כ) in instances when the letter is voiceless.
