Speech-to-speech translation turns spoken words in one language into spoken words in another: someone talks, or a video plays, and you hear it in your language — no typing, no subtitles to read. DubMog does it in real time on iPhone, Android and the web, and in Chrome and Microsoft Edge on a computer. Here's how it works, what's new with iOS 27, and how to set it up in a minute.
What speech-to-speech translation is
Three things happen in a row, live: the speech is recognised, translated, and spoken again in your language with a natural AI voice. DubMog runs that chain while the person is still talking, so you hear the translation a couple of seconds behind the speaker, with the original ducked underneath and a running transcript on screen.
That's the difference from a subtitle app or a text translator: your eyes stay on the conversation or the scene, and your ears do the work.
Where DubMog does it
- Conversations and meetings. Hold the mic button on the main screen and speak — DubMog detects the language and speaks the translation back through the speaker, in 80+ languages.
- Videos you own. Dub a File takes a video from Photos or Files and hands back a finished, dubbed copy to save or share — no need to watch while it works.
- Other apps on iPhone. Live System Dub speaks the audio another app is playing in your language. Apps that protect their audio come through silent, and DubMog tells you so instead of charging.
- Any browser tab on a computer. The DubMog extension for Chrome and Microsoft Edge dubs videos, online courses, calls and streams as they play.
Ready for iOS 27 and the new iPhones
iOS 27 arrived this month, and DubMog runs on it — the app supports iOS 26.4 and later, and we've tested our next update on iOS 27.
iPhone 18 Pro and iPhone 18 Pro Max ship with iOS 27, so DubMog runs on them from day one, including on the 18 Pro Max's bigger screen.
iPhone Duo, Apple's first foldable iPhone, opens to a 7.6-inch inner display and has a 5.4-inch display on the outside. It ships with iOS 27 — preorders start October 16 and it's available October 23. A screen that size is a very good place to watch a dubbed video, and we'll test DubMog on iPhone Duo as soon as it's in hand.
Install DubMog on iPhone
- Download DubMog free from the App Store.
- Open it and tap Continue — allow the microphone and speech recognition when iOS asks.
- Pick the language you want to hear, then press and hold the mic button to translate a conversation — or tap Dub a Video to dub a clip.
On a computer: Chrome and now Microsoft Edge
The DubMog browser extension listens to the tab you're on and speaks it back in your language as it plays, with a transcript beside it. It's free on the Chrome Web Store and now on Microsoft Edge Add-ons, with a free taste every day. Sign in with the same Apple, Google or email account as the app and your minutes and Pro follow you.
