Original sentence: In the speech of Ashkenazi Modern Hebrew speakers, the phoneme /x/ is represented by two letters: xet (ח) and khaf (כ, assumed to have formerly formerly been an aspirated kaf).Xet is presumed to historically have been a voiceless pharyngeal fricative (like Arabic ح), a pronunciation is found in the speech of many Teimanim, Mizrachim and Sephardim
Edited sentence: Although Modern Hebrew speakers seldom differentiate between the two, apart from a few Sephardic speakers, the former was historically a voiceless pharyngeal fricative (like Arabic ح).The phoneme /x/ is represented by two letters: xet (ח) and khaf (כ, unemphasized kaf)
