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.
Judeo-Yemeni Arabic
Judeo-Yemeni Arabic (also known as Judeo-Yemeni and Yemenite Judeo-Arabic) is a variety of Arabic spoken by Jews living or formerly living in Yemen. The language is quite different from mainstream Yemeni Arabic, and is written in the Hebrew alphabet. The cities of Sana'a, Aden, al-Bayda, and Habban District and the villages in their districts each have (or had) their own dialect.
