How to Create Professional Training Videos in Multiple Languages Using Synthesia
Hey — Eli Mercer here. I help solopreneurs and small teams stay ahead of the curve by putting new AI tools to the test so you don’t waste time on tech that doesn’t deliver.
Today I’m breaking down how I used Synthesia to build pro-level training videos in multiple languages using nothing but text, AI avatars, and a standard laptop.
So if you’re a training manager, L&D specialist, or entrepreneur who’s tired of hiring voice actors, editing long videos, or chasing down localization partners… keep reading.
You’re about to learn how to skip the camera crew and scale your training program to global audiences—all in less than an afternoon.
Why Traditional Training Video Creation Is Broken ❌
- Shooting video takes days (sometimes weeks)
- Multiple language versions = double or triple the cost
- You need cameras, actors, editors, studios
- Updating one sentence in a video means starting over
If you’ve built training content, you know it’s a headache from start to finish. Even a minor policy update can throw your onboarding videos out of sync (and drive your team nuts).
How Synthesia Changes the Game 🚀
Synthesia is an AI video creation tool that turns text into training videos in over 140 languages. It uses realistic AI avatars to “speak” your script like a real teammate would—only they never call out sick or forget their lines.
And no, it’s not some stiff robotic voice. These avatars are lifelike, professional, and 100% customizable. You can even create a digital twin of yourself if you want to appear onscreen.
The best part? You don’t need editing skills, video production knowledge, or fancy gear. If you can write an email, you can make a training video with Synthesia.
How to Create a Training Video with AI Avatars (Step-by-Step)
This is the exact workflow I use when creating onboarding and compliance videos for clients across different countries. You can do this even if you’ve never used video tools before.
Step 1: Write Your Script
Keep it short and focused. If it takes more than 3–5 minutes to get through, break the video into smaller modules. Synthesia is optimized for microlearning content.
Pro Tip: Use Synthesia’s AI script generator if you’re drawing a blank. It’s shockingly good at kicking things off.
Step 2: Choose an AI Avatar
You can choose from 230+ avatars—everything from professional business personas to casual and friendly styles. You can even filter by accent or region to match your brand tone.
Optional: Upload your own digital avatar to keep the brand consistent or introduce yourself in every video.
Step 3: Select Voice Language
140+ languages. No joke. From English and Spanish to Vietnamese, Swahili, and Hindi—pick your target market and let Synthesia do the voiceover work in a native-sounding voice.
Step 4: Add Visual Elements
Drop in your logo. Apply brand fonts and colors. Use on-screen text and icons to reinforce key points. You can also upload slides or screenshots if you’re demoing software or workflows.
Step 5: Preview & Publish
Watch the AI take your script and render it as a full training video—voiceover, avatar, visuals, all done for you. From there, you can download it or export for your LMS (SCORM-compatible).
Real-World Results: What I Saved Using Synthesia
Before Synthesia, this is what a typical 5-minute training video cost me as a contractor:
- Voice actor: $150
- Editor: $300+
- Studio time or screen rec tools: $99/month
- Translation per language: $200+
That’s over $700 per video, not counting revisions.
With Synthesia, I now create the same training module for 5 languages in under 2 hours—all for a fraction of the price with the Starter plan (around $22/month).
No extra software, no freelancers, no headaches.

FAQs About Creating AI Training Videos
Is Synthesia suitable for companies with strict branding?
Yes. You can customize fonts, colors, logos, backgrounds, and even the avatar that represents your team. It’s like having an in-house video department, but scalable.
Can I edit my video after publishing?
Absolutely. You can go back, change the text, update visuals, switch avatars, or translate the same video to other languages—without starting from scratch.
Is the content SCORM or LMS compatible?
Yes, you can export as SCORM files or video formats compatible with most popular learning management systems (LMS).
How many languages does Synthesia support?
As of now, Synthesia’s AI voiceover system handles 140+ languages and accents—including region-specific options for even better localization.

Final Thoughts: Should You Use Synthesia for Training?
If you need high-quality training videos and want to cut production time by 90%, reach global teams instantly, and never book another studio again—yes, Synthesia is a no-brainer.
It took me from spending over $1,000/video to building full onboarding sequences in multiple languages—all before lunch.
Whether you’re a solopreneur scaling your content, an HR lead in a global company, or a marketer who needs repeatable video templates—
See what AI video can do for your training workflows. You’ll be shocked by how far tech has come.
