Guttural R
Many Jewish immigrants to Israel spoke a variety of Arabic in their countries of origin and pronounced the Hebrew rhotic as an alveolar tap , similar to Arabic '. Gradually, many of them began pronouncing their Hebrew rhotic as a voiced uvular fricative , a sound similar or (depending on the Arabic dialect) identical to Arabic '. However, in modern Sephardic and Mizrahi poetry and folk music an alveolar rhotic continues to be used.

Although the vast majority of post-Biblical Hebrew and Aramaic words are pronounced the same way or nearly the same way by all of Israel's diverse ethnic groups, including the Jews of Yemen, there are still other words whose phonemic system differs greatly from the way it is used in Modern Hebrew, the sense here being the tradition of vocalization or diction of selective Hebrew words found in the Mishnah and Midrashic literature, or of Aramaic words found in the Talmud, and which tradition has been meticulously preserved by the Jews of Yemen. The following diagrams show a few of the more conspicuous differences in the Yemenite tradition of vocalization and which Israeli linguist, Shelomo Morag, believes reflects an ancient form of vocalizing the texts and was once known and used by all Hebrew-speakers.
