Libera TranScribe is a revolutionary new application that transforms any unvocalized Arabic text by adding vowels to it, providing a powerful environment for learners by placing the unvocalized Arabic text alongside vocalized, romanized, and translated versions of the same text in a single, convenient view.

Unvocalized Arabic is notorious for its ambiguity. Its lack of vowel diacritics means that words can be pronounced in a multitude of possible ways. For example, the unvocalized word كاتب, can be pronounced in seven different ways, including كَاتِب kātib, كَاتَبَ kātaba and كَاتِبَ kātiba. This "Vowel Barrier" is no doubt one of the greatest obstacles for learners of Arabic, which is already one of the world’s most challenging languages.

Libera TranScribe allows you to paste in Arabic text from any source, such as email or articles on news sites like BBC Arabic, or to type in your own Arabic using the built-in Arabic keyboard.

Libera TranScribe provides a high-quality text-to-speech audio feature that allows learners to reinforce their pronunciation while beginning learners can use the audio and romanization to learn to read vocalized Arabic script. For ease of use, corresponding sentences in the various panels are clearly indicated, and the three Arabic texts (unvocalized Arabic, vocalized Arabic and romanized Arabic using our unique CARS system), and the corresponding audio are precisely linked at the word level. This means that tapping on a word in one text simultaneously highlights the linked word in each of the other texts and optionally plays the audio for that word.

Together, these five elements -- vocalized and unvocalized Arabic, CARS romanization, translation and audio -- arm the Arabic learner with a powerful tool for acquiring the language rapidly and with ease.

-- Works with any Arabic text of the user's choice
-- Adds vowel diacritics to any unvocalized Arabic text
-- Provides user-friendly romanization to any unvocalized Arabic text
-- Translates any Arabic text into English or dozens of other languages

The best Arabic reading app so far!

I have been teaching Arabic for the last 12 years in different parts of the world to different nationalities with different purposes. I believe that this application is one of the best, if not the best, reading application I have used in my professional life. The grammatical accuracy is spectacular, especially for an Arabic teacher who used to rather critique towards various Arabic reading apps. The translation into English, romanization and perfectly pronounced Arabic are done simultaneously with no single error. I have recommended Libra TranScribe to all my students as well as my fellow teachers as the ultimate reading assistance and translation tool. It works marvelously with all kinds of purposes. As a tourist for example you can use it in various situations and will never fail you. I would suggest further developments regarding the camera reading feature.

Hiyat ,

Before you translate a single thing....

You have to buy credits to transcribe. There are packs that you have to buy AND you have to sign up to use the app. Will be getting deleted!
