Abstract: The invention relates to the vowelization of an Arabic language text, aided by computerized means. According to the invention, a first dictionary (D1) comprising unvowelized words is provided, and a second dictionary (D2) comprising groups of at least one vowelized word is provided, each group being stored in correspondence with an unvowelized word. For a current unvowelized word, a string of characters forming the current word is compared with strings of characters stored in the first dictionary, and a group of vowelized candidate words corresponding to the word identified from the first dictionary is extracted from the second dictionary.
