ElevenLabs vs Sync Labs
ElevenLabs and Sync Labs are often compared, but they solve fundamentally different problems. ElevenLabs is a text-to-speech, voice cloning & dubbing platform built for voice cloning projects. Sync Labs focuses on ai lip sync engine (not a full dubbing pipeline), making it a better fit for developers building video localization pipelines. We tested both platforms to break down where each one excels and where it falls short.
The Key Difference
Sync Labs includes visual lip sync that adjusts mouth movements to match the translated audio. ElevenLabs does not offer lip sync at all — it focuses exclusively on audio quality. This is the core trade-off: Sync Labs delivers a complete dubbed video, while ElevenLabs produces higher-fidelity audio that you would need to pair with your original video, accepting the visible lip-audio mismatch.
Feature Comparison
When comparing features, pay attention to more than just checkboxes. ElevenLabs supports 29+ languages and Sync Labs offers 100+ — 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 | Sync Labs |
|---|---|---|
| Primary Focus | Text-to-speech, voice cloning & dubbing | AI lip sync engine (not a full dubbing pipeline) |
| Languages | 29+ | 100+ |
| Lip Sync | ✗ No | Yes (Good) |
| Voice Cloning | ✓ Yes | ✓ Yes |

| API Access | ✓ Yes | ✓ Yes |
| Multi-Speaker | N/A | Auto detection |
| Custom Vocabulary | ✗ No | ✗ No |
| Unlimited Revisions | ✗ No | ✗ No |
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 Sync Labs charges via subscription + per-second usage ($0.04–$0.083/sec) starting at $5/month + usage. The real cost depends on your volume, whether you need lip sync (which often costs extra), and how many team members need access.
