Face-to-face translation on iPhone: how DuoTalk is designed
Why a conversation translator should keep both languages in view, how DuoTalk handles speech and text, and its translation limits.
In this guide5
The problem with passing one phone back and forth
A conversation between two languages becomes awkward when one screen, one microphone and one translation box serve both people. Each person waits, reads over the other's shoulder, and loses track of which phrase was theirs. DuoTalk starts from that frustration: the layout keeps each language visible on its own side of the conversation.
Two languages, one exchange
The screen keeps each language on its own side, showing the original phrase and its translation. Face-to-face mode rotates the top half so both people can read from opposite sides of the device. DuoTalk targets iPhone and iPad with iOS 18 or later.
Speak, type or review
A useful exchange needs more than a microphone button. DuoTalk is built around deliberate actions: choose the two languages, hold to speak or type a phrase, read the translation, and play it aloud only if you want to. The microphone listens only while the button is held, and nothing is recorded to a file.
Translation on the iPhone
Text is translated by Apple Translation on the device once any required language resources are downloaded. DuoTalk offers 20 translation languages. Language pairs, speech recognition and voices depend on the device and iOS version. No DuoTalk account is required; the current conversation stays on the device and can be cleared.
