Best AI Dubbing Apps for iPhone

AI dubbing takes the speech in your video, translates it and reads it back in a generated voice. On an iPhone, a few apps do the whole thing without a computer. The main differences between them are whether they change your lips to match, whether the new voice sounds like you, and the price.

One of the apps below, CapCap, is the app we make. Prices are the in-app purchases listed on the US App Store, checked on October 17, 2026.

Lip sync or not?

This is the first thing to decide.

• With lip sync, the app regenerates the video so your mouth moves with the new language. It matters when your face fills the frame. It's also slower and costs more.
• Without lip sync, only the audio changes. That's fine for voice-overs, tutorials, screen recordings, product demos and anything where the speaker is small in the frame or off camera.

1. HeyGen: Translate Video

HeyGen Translate is the most complete dubbing app on this list. Its App Store description says it dubs into 175+ languages, clones your voice, re-syncs your lips to the translated speech and handles videos with more than one speaker. There's also an audio-only option if you don't want the video regenerated.

• Good for: talking-head videos where you're on camera, speaking to the viewer.
• Watch out for: it's the priciest option here, and dubbing uses credits.
• Price: HeyGen Creator is listed at $10 a week, $29 a month or $279 a year, with credit packs from $4.99.

2. Captions (by Mirage)

Captions is an AI video editor, and its App Store description lists AI dubbing into 29 languages next to subtitles in 91+. Its website also lists a lip-sync feature (AI Lipdub), though it doesn't make clear which plan includes it.

• Good for: creators who want dubbing inside a full AI editing app.
• Watch out for: fewer dubbing languages than HeyGen, and you'll be paying for a whole editor.
• Price: Captions Basic is listed at $9.99 a month or $64.99 a year, and Captions Max at $24.99.

3. CapCap

CapCap transcribes your video, translates it and generates a voice that reads the translation, along with subtitles in the new language. For the voice, you can let it pick one that matches the speaker (Auto), use Original voice, which is modeled on the speaker's own voice, or choose and preview a voice yourself.

• Good for: voice-overs, tutorials and demos, and anyone who wants dubbed audio and editable subtitles from the same project.
• Watch out for: no lip sync. Close-ups of someone talking will look out of sync. iPhone only, iOS 18 or later.
• Price: the free plan gives 3 captioned videos a month, up to 3 minutes each, with a small watermark. Pro is $14.99 a month or $59.99 a year.

How to dub a video in CapCap

Which one to pick

• You're on camera and it has to look natural: HeyGen.
• You want dubbing inside an all-in-one editor: Captions.
• Voice-overs and demos, plus subtitles, for less: CapCap.

Tips for any dubbing app

• Start with clean audio. Background music and people talking over each other make the transcription worse, and the dub follows the transcription.
• Listen to the whole result once. Some languages need more words to say the same thing, so a line can run past its moment.
• Have someone who speaks the language watch your first few videos before you post them.

If you'd rather keep your own voice, translated subtitles are the cheaper route. See the best apps to translate video subtitles on iPhone.
