How to Localize an Online Course into Arabic with AI: Glossary, Dubbing, Slides and Subtitles

01What it takes to localize an online course to Arabic

You have an English course that works: videos, slides, quizzes and downloads. Now you want to sell it in Saudi Arabia, Egypt or the UAE. Translation alone won't get you there. Arabic-speaking learners need to hear the lesson in a clear Arabic voice, see the same term in the video, the slide and the quiz, and feel the examples were written for them. That's the gap between translation and localization.

This guide is about localizing a course that already exists. If you're authoring a new Arabic course and narrating it with AI from scratch, our e-learning text to speech guide covers that workflow.

Start with an inventory. This table shows what needs localizing and where it happens:

02Build the glossary before you translate a word

Nothing confuses learners more than one concept with three Arabic names: one word for dashboard in lesson one, a transliteration in lesson two, and something else in the quiz. Write the glossary first, have a subject-matter expert approve it, then hold every asset to it.

Vocla's dubbing studio has a glossary with two kinds of entries: terms to keep as they are, such as software and brand names, and terms always translated one way. It applies during translation and in every line rewrite. Pronunciation lives in the workspace pronunciation dictionary: enter KPI with the reading كيه بي آي, and every voice says it the same way in dubbing and in text to speech.

Use the same document for cultural decisions. Prices in case studies move from dollars to riyals, dirhams or pounds depending on the audience; characters become familiar Arabic names such as Sara, Khalid and Noura; and an example built around a Western holiday can become Ramadan trading or back-to-school season. These small choices are what make a learner feel the course was written for them.

03Dub the video, or re-voice from a translated script?

There are two routes to Arabic audio. Dubbing takes the video as it is: Vocla detects the speakers, writes a timed Arabic script against the instructor's speech and voices it. Re-voicing means translating the narration script, generating new audio in text to speech, and laying it under the video in your editor.

Most teams mix the two: dub talking-head lessons and re-voice screen demos, where the narration must follow exactly what's on screen. Vocla dubs voice-over style without lip-sync, which is usually fine for courses because the instructor rarely fills the frame for long.

Watch line length. Arabic translations often run longer than the English, and in a dub the Arabic has to fit roughly where the original line sat. That's why Vocla writes a voice-over adaptation with short lines rather than a literal translation, and flags overlong lines in the Problems panel. Re-voicing gives you more room: explain an idea in two sentences instead of one and extend the clip in your editor.

04MSA or your learners' dialect?

Academic and professional courses aimed at several countries usually choose simple Modern Standard Arabic, which everyone understands and which carries technical terms well. Short courses for a defined audience, such as sales training in Riyadh or a marketing course for Cairo founders, often land better in dialect.

Both say “In this lesson we'll learn how to add a lead to the dashboard, then follow it through to the sale.” The glossary terms stay identical in both. You don't have to choose once, either: duplicate a dubbing project into another dialect in one click, reusing the transcript and speakers with no new analysis. Ship an MSA edition for everyone and an Egyptian edition for a corporate client in Cairo.

05The dubbing workflow in Vocla, lesson by lesson

1. 1Upload the lesson: pick the spoken language and the Arabic target: MSA, Saudi, Emirati, Kuwaiti, Egyptian, Jordanian or Lebanese.
2. 2Check the speakers: Vocla detects who speaks when and casts a voice for each. Rename the instructor so the script is easy to follow.
3. 3Add the glossary: enter keep-as-is and fixed-translation terms before you review.
4. 4Fix long lines: the Problems panel lists every line too long for its slot and suggests shorter wording you approve.
5. 5Choose the background: Keep background lowers the original under the Arabic; Voice only gives a clean Arabic track. Try both on lessons with music or software sounds.
6. 6Export: MP4 with the Arabic track, MP4 with burned-in Arabic subtitles, MP3, WAV, and SRT and VTT in Arabic and the original language.

06Slides, subtitles and getting it into your LMS

Vocla replaces the audio and adds subtitles, but it doesn't edit text drawn inside the picture. If your slides carry English titles and bullets, localize them in your authoring or slide tool and re-export the video before dubbing. Mirror the layout for Arabic: titles start on the right and arrows point the right way.

• Burned-in subtitles: always visible, useful when your platform doesn't support subtitle files.
• SRT or VTT: learners can toggle them, and most LMSs and web players accept them.
• Bilingual subtitles: Arabic and English together, handy when learners must also know the English term.
• Audio only: for platforms that allow a second audio track on the same video.

After export, upload the MP4 and subtitle files to your LMS or site yourself, like any other video. Vocla has no direct LMS connection, so use clear file names such as module-02-lesson-03-ar.mp4 and module-02-lesson-03-ar.srt to keep versions straight.

Don't forget what surrounds the video. Quizzes must use the glossary terms, because a learner who heard عميل محتمل in the lesson will stumble over a transliterated “lead” in the question. Worksheets need right-to-left layout, tables that start on the right and a clear Arabic font. Keep module and lesson titles short, since they appear in sidebars and on phones.

07Review, updates and cost

Before publishing, have a subject-matter expert watch a full lesson in Arabic rather than just reading the script. They'll hear whether terms are right, timing is comfortable and names and numbers are said properly. If a voice misreads a recurring word, add it to the pronunciation dictionary once instead of fixing it lesson by lesson.

• Terminology: does every term in the audio and subtitles match the glossary?
• Timing: does the Arabic explanation start when the slide or step appears?
• Pronunciation: are software names, acronyms and numbers read correctly?
• Subtitles: are lines short, readable on a phone and right to left?
• Background: does the lowered original audio distract, or is Voice only better?
• Slides: is every visible text now Arabic, or deliberately kept in English?

Updates are where AI saves the most. The software you teach changed a menu? Edit that line and re-render: you only pay for lines you changed, and timing or pace tweaks alone don't re-voice anything. Dubbing is charged by characters voiced plus a small per-minute processing fee, and you see the exact cost before every render.

Terms and examples here are illustrative. The Free plan has no commercial rights, so paid courses and corporate training need Starter or above.
