After the expulsion of the Sephardi Jews from Spain in 1492, the exiles took the leading position in most Arab and Ottoman countries, and the local pronunciation of Hebrew assimilated to Sephardi Hebrew in many respects, particularly for pronouncing the vowels. Today's Iraqi Jews distinguish between "patach" () and "segol" () in the same way as most other Sephardi and Mizrahi Jews. However, distinct sounds for the guttural and emphatic letters and the sound for "bet rafe" were retained in many Arab countries, probably under the influence of Arabic.
