The recording is the Purim song “And it was in the days of Achashveirosh…” sung in Jewish Neo-Aramaic in Jerusalem.
Jewish Neo-Aramaic languages refer to a group of severely endangered dialects of the Semitic language Aramaic. Two dialects spoken especially among Kurdish Jewish populations include Barzani Jewish Neo-Aramaic (Lishanid Janan) and Betanure Jewish Neo-Aramaic (Lishana Deni). The Barzani dialect originated in 3 villages near Aqrah in Iraq, but today it is spoken by approximately 20 individuals in Jerusalem. The Betanure dialect was originally spoken in the Jewish Kurdish village of Betanure (now populated by Assyrians) in Iraqi Kurdistan. The current number of speakers is unknown, but it is estimated that there are at most 3 dozen located in Israel. These dialects are some of the most severely endangered of the Jewish languages and dialects currently spoken.
Jewish Neo-Aramaic dialects were usually mutually intelligible with the dialects spoken by non-Jewish neighbors with some exceptions of vocabulary borrowed from Hebrew and rabbinical Aramaic texts. This use of vocabulary was at times deliberate in order for Jews to speak to one another without being understood by their Christian and Muslim peers.
