Sephardi Hebrew
Sephardi Hebrew (or Sepharadi Hebrew) is the pronunciation system for Biblical Hebrew favored for liturgical use by Sephardi Jewish practice. Its phonology was influenced by contact languages such as Spanish, Judaeo-Spanish (Ladino), Arabic, Portuguese and Modern Greek. Phonology. There is some variation between the various forms of Sephardi Hebrew, but the following generalisations may be made: This last difference is the standard shibboleth for distinguishing Sephardi from Ashkenazi, Yemenite, and Tiberian Hebrew. The differentiation between kamatz gadol and kamatz katan is made according to purely phonetic rules, without regard to etymology, which occasionally leads to spelling pronunciations  at variance with the rules laid down in Biblical Hebrew grammar books. For example, כָל (all), when unhyphenated, is pronounced "kal", rather than "kol" (in "kal 'atsmotai" and "Kal Nidre"), and צָהֳרַיִם (noon) is pronounced "tsahorayim", rather than "tsohorayim". This feature is also found in Mizrahi Hebrew, but is not found in Israeli Hebrew. It is represented in the transliteration of proper names in the Authorised Version, such as "Naomi", "Aholah" and "Aholibamah". Letter pronunciation. Consonants Vowels Variants. Sephardim differ on the pronunciation of "bet raphe" (, "bet" without "dagesh"). Persian, Moroccan, Greek, Turkish, Balkan and Jerusalem Sephardim usually pronounce it  as , which is reflected in Modern Hebrew. Spanish and Portuguese Jews traditionally pronounced it as (as do most Mizrahi Jews), but that is declining under the influence of Israeli Hebrew. That may reflect changes in the pronunciation of Spanish. In Medieval Spanish (and in Judaeo-Spanish), "b" and "v" were separate, with "b" representing a voiced bilabial stop and "v" realized as a bilabial fricative [β]. However, in Renaissance and modern Spanish, both are pronounced (bilabial v) after a vowel (or continuant) and otherwise (such as after a pause). There is also a difference in the pronunciation of "tau raphe  (, tau" without "dagesh"): Closely related to the Sephardi pronunciation is the Italian pronunciation of Hebrew, which may be regarded as a variant. In communities from Italy, Greece and Turkey, "he" is not realized as but as a silent letter because of the influence of Italian, Judaeo-Spanish and (to a lesser extent) Modern Greek, all of which lack the sound. That was also the case in early transliterations of Spanish-Portuguese manuscripts ("Ashkibenu", as opposed to "Hashkibenu"), but "he" is now consistently pronounced in those communities. Basilectal Modern Hebrew also shares that characteristic, but it is considered substandard. In addition  to ethnic and geographical distinctions, there are some distinctions of register. Popular Sephardic pronunciation, such as for Spanish and Portuguese Jews, makes no distinction between "pataḥ" and "qameṣ gadol" [a], or between "segol", "ṣere" and "shewa na" [e]: that is inherited from the old Palestinian vowel notation. In formal liturgical use, however, many Sephardim are careful to make some distinction between these vowels to reflect the Tiberian notation. (That can be compared to the attempts of some Ashkenazim to use the pharyngeal sounds of "ḥet" and "ayin" in formal contexts, such as reading the Torah.) History. There have been several  theories on the origins of the different Hebrew reading traditions. The basic cleavage is between those who believe that the differences arose in medieval Europe and those who believe that they reflect older differences between the pronunciations of Hebrew and Aramaic in different parts of the Fertile Crescent: Judaea, Galilee, Syria, northern Mesopotamia and Babylonia proper. Within the first group of theories, Zimmels believed that the Ashkenazi pronunciation arose in late medieval Europe and that the pronunciation prevailing in France and Germany during the Tosafists was similar to the Sephardic. He noted that Asher ben Jehiel, a German who became  chief rabbi of Toledo, never refers to any difference of pronunciation though he is normally very sensitive to differences between the two communities. The difficulty with the second group of theories is that it is uncertain what the pronunciations of the countries actually were and how far they differed. Since the expulsion of the Jews from Spain in 1492, if not earlier, the Sephardic pronunciation of the vowels became standard in all those countries, ironing out any differences that previously existed. That makes it harder to adjudicate between the different theories on the relationship between today's pronunciation systems and  those of ancient times. Leopold Zunz believed that the Ashkenazi pronunciation was derived from that of Palestine in Geonic times (7th-11th centuries) and that the Sephardi pronunciation was derived from that of Babylonia. The theory was supported by the fact that in some respects, Ashkenazi Hebrew resembles the western dialect of Syriac, and Sephardi Hebrew resembles the eastern dialect: Eastern Syriac "Peshitta" as against Western Syriac "Peshito". Ashkenazi Hebrew, in its written form, also resembles Palestinian Hebrew in its tendency to "malē" spellings (see Mater lectionis). Others, including Abraham Zevi Idelsohn, believed that the distinction is more ancient and represents  the distinction between the Judaean and Galilean dialects of Hebrew in Mishnaic times (1st-2nd centuries), with the Sephardi pronunciation being derived from Judaean and the Ashkenazi from Galilean. The theory is supported by the fact that Ashkenazi Hebrew, like Samaritan Hebrew, has lost the distinct sounds of many of the guttural letters, and there are references in the Talmud to that as a feature of Galilean speech. Idelsohn ascribes the Ashkenazi (and, on his theory, Galilean) pronunciation of qamats gadol as to the influence of Phoenician: see Canaanite shift. The 14th century, German Jewish work, Sefer Asufot seems to suggest  that medieval Ashkenazi Hebrew was much akin to medieval Sephardi Hebrew. In the time of the Masoretes (8th-10th centuries), there were three distinct notations for denoting vowels and other details of pronunciation in biblical and liturgical texts. One was the Babylonian; another was the Palestinian; still another was the Tiberian, which eventually superseded the other two and is still in use today. Of them, the Palestinian notation provides the best fit to the current Sephardi pronunciation; for example, it does not distinguish between "pataẖ" and "qamats" or between "segol" and "tsere". (Similarly, the Babylonian notation appears to fit the Yemenite  pronunciation.) The Tiberian notation does not quite fit any pronunciation in use today, but the underlying pronunciation has been reconstructed by modern scholars: see Tiberian vocalization. (A variant of the Tiberian notation was used by Ashkenazim before it was superseded by the standard version.) By the time of Saadia Gaon and Jacob Qirqisani, the "Palestinian" pronunciation had come to be regarded as standard, even in Babylonia (for references, see Mizrahi Hebrew). That development roughly coincided with the popularisation of the Tiberian notation. The accepted rules of Hebrew grammar were laid down in medieval Spain by grammarians such as Judah ben  David Hayyuj and Jonah ibn Janah and later restated in a modified form by the Kimhi family; the current Sephardic pronunciation largely reflects the system that it laid down. By then, the Tiberian notation was universally used though it was not always reflected in pronunciation. The Spanish grammarians accepted the rules laid down by the Tiberian Masoretes, with the following variations: There are further differences: In brief, Sephardi Hebrew appears to be a descendant of the Palestinian tradition, partially adapted to accommodate the Tiberian notation and further influenced by the pronunciation of Arabic, Spanish and Judaeo-Spanish (Ladino). Influence on  Israeli Hebrew. When Eliezer ben Yehuda drafted his Standard Hebrew language, he based it on Sephardi Hebrew, both because this was the "de facto" spoken form as a lingua franca in the land of Israel and because he believed it to be the most beautiful of the Hebrew dialects. However, the phonology of Modern Hebrew is in some respects constrained to that of Ashkenazi Hebrew, including the elimination of pharyngeal articulation and the conversion of from an alveolar tap to a voiced uvular fricative, though this latter sound was rare in Ashkenazi Hebrew, in which uvular realizations were more commonly  a trill or tap, and in which alveolar trills or taps were also common.
