ElevenLabs vs Synthesia
ElevenLabs and Synthesia are often compared, but they solve fundamentally different problems. ElevenLabs is a text-to-speech, voice cloning & dubbing platform built for voice cloning projects. Synthesia focuses on ai avatar video generation (dubbing is a secondary feature), making it a better fit for enterprise l&d and training videos. We tested both platforms to break down where each one excels and where it falls short.
The Key Difference
Synthesia is an avatar-first platform that added video translation as a secondary feature. ElevenLabs is purpose-built for dubbing real footage. This architectural difference shows up everywhere: ElevenLabs's lip sync is optimized for real human faces and natural speech patterns, while Synthesia's lip sync engine was designed for synthetic avatars and can struggle with occlusions, rapid movement, and complex real-world footage.
Feature Comparison
When comparing features, pay attention to more than just checkboxes. ElevenLabs supports 29+ languages and Synthesia offers 130+ — but raw language count is less important than quality in your target languages. Look at lip sync ratings, multi-speaker handling, and whether the platform produces finished video or just audio tracks.
| Feature | ElevenLabs | Synthesia |
|---|---|---|
| Primary Focus | Text-to-speech, voice cloning & dubbing | AI avatar video generation (dubbing is a secondary feature) |
| Languages | 29+ | 130+ |
| Lip Sync | ✗ No | Yes (Good) |
| Voice Cloning | ✓ Yes | ✓ Yes |
| Video Output | ✓ Yes | ✓ Yes |
| Avatar Creation | ✗ No | ✓ Yes |
| API Access | ✓ Yes | ✓ Yes |
| Multi-Speaker | N/A | Auto detection |
| Custom Vocabulary | ✗ No | ✗ No |
| Unlimited Revisions | ✗ No | ✓ Yes |
Pricing
Pricing in the AI dubbing space is notoriously hard to compare apples-to-apples. ElevenLabs uses a credit-based model starting at $5/month, while Synthesia charges via credit-based tiers starting at $18/month. The real cost depends on your volume, whether you need lip sync (which often costs extra), and how many team members need access.

| Starting Price | $5/month | $18/month |
| Pricing Model | Credit-based | Credit-based tiers |
| Free Tier | ✓ Yes | ✓ Yes |

Data Privacy & Compliance
Data privacy is where these two platforms differ significantly. Synthesia processes data on EU servers in EU (AWS Ireland/Frankfurt) with a full GDPR infrastructure including DPA and no AI training on customer data. ElevenLabs processes data on servers in USA (New York). For European enterprises or anyone handling sensitive content, this section deserves careful attention.

| Server Location | USA (New York) | EU (AWS Ireland/Frankfurt) |
| DPA Available | ✗ No | ✓ Yes |
| No AI Training | ✗ No | ✗ No |
