The distinctive Babylonian pronunciation of Geonic times is still preserved by Yemenite Jews, but they do not retain the Babylonian notation. In Iraq, it appears to have been superseded by the Palestinian pronunciation (similar to today's Sephardi Hebrew) in or around the 11th century, when the Tiberian notation was adopted: both Saadia Gaon and Jacob Qirqisani report that in their time the Palestinian pronunciation had come to be regarded as standard. Nevertheless, in their reading of unvocalised texts such as the Mishnah, Baghdadi Jews preserve certain peculiarities of the old Babylonian pronunciation, particularly with their choices between "dagesh" and "rafe" and between silent and vocal "sheva".
