Common questions

Is Cartesia Sonic-3 better than Deepdub for dubbing a YouTube video?

No. Deepdub is built for video dubbing with lip-sync and multi-speaker handling. Cartesia is just a voice generator – you'd have to manually sync the audio to your video, which is tedious.

Can I use Cartesia Sonic-3 on my phone?

No, there is no mobile app. You can access the web-based Playground from a phone browser, but it's not optimized for mobile use.

Which tool is cheaper for a hobbyist?

Cartesia Sonic-3. It has a free tier and paid plans from $4/month. Deepdub's pricing is aimed at professionals and studios, so it's not affordable for casual use.

Does Deepdub work if the person in the video is not facing the camera?

No, DeepSync requires clear face visibility to adjust lip movements. If the speaker is off-screen or their face is obscured, lip-sync won't work.

Can I clone my own voice with Cartesia Sonic-3?

Yes, you can generate a 10-second instant voice clone or request a Pro Voice Clone, but the advanced clone may require manual review.

Which tool is better for a beginner who just wants to make audio books?

Cartesia Sonic-3. It's simple, cheap, and produces natural-sounding speech with emotion. Deepdub is overkill for audio-only projects.

Cartesia Sonic-3 is the practical, affordable choice for everyday voice generation; Deepdub is a powerful but expensive studio tool for video dubbing.

If you're a regular person who wants to turn text into natural-sounding speech without breaking the bank, go with Cartesia Sonic-3 – it's fast, cheap, and easy. Leave Deepdub to the pros who need to dub entire movies with perfect lip-sync.
