Abstract
A device capable of words/sentences translation from Arabic languages (Arabic, Urdu and Persian) to another language and vice-versa. The device discloses word pronunciation means which incorporate a sound synthesis means, a storage means for coded allophones and firmware means for language pronunciation rules. The invention discloses a data structure means and input means that eliminates the need for alphabetic keyboards. The device discloses a display means for words, modifiers, and explanatory abbreviations to categorize words. The invention also discloses a variable-width dot-matrices means for Arabic letters/modifiers generation. In one embodiment, the device contains a single chip microcomputer, a liquid crystal dot matrix display, a voice synthesis processor, a six-key operation keyboard and a solid state memory module for Arabic-English and English-Arabic translation.
