Hebrew as Arabic can be read either voweled or unvoweled. However the literacy Hebrew is voweled, which turns it in a shallow / transparent orthography. The pronunciation of syllables in Hebrew rarely varies as a function of specific letter strings, position in the word and the nature of the vowels used. The acquisition of GFC rules and decoding of voweled Hebrew requires the learner to master few rules, and fewer "exception words".
Usually, beginner readers learn the voweled Hebrew and by the time they have reached the 5-6 grade they are given unvoweled texts (Geva & Siegel, 2000). This means that they are ready to read without the complement of vowels (they are supposed to have automatized the decoding) and that they are able to read within an opaque orthography.
