The MULTIVOX-Multilingual text-to-speech converter system is adapted to Modern
Standard Arabic. In this system, Arabic speech is generated from the concatenation
of a set of acoustic building units (ABUs). A 3-dimensional data-base rule-system for the
synthesis of unlimited vocabulary Arabic text is organized to concatenate the appropri-
ate ABUs for all possible phone-code pairs that may exist in the input text. The main
functions of the MULTIVOX are explained. Illustrative examples are given to show the
conversion of Arabic graphemes into phone-codes and the use of the data-base rule-system
in the concatenation of the ABUs. Hearing tests have been carried out to test the quality
of the synthesized speech
