A feature you won't find in ordinary calling apps: what the other person says appears written and translated on your screen during the call.
Steps:
- During the call tap Translate.
- The first time with each person choose: I speak (the app language by default) and The other person speaks (detect automatically).
- Tap Start translation. You can turn it on before they answer and it starts when they do.
- Long-press the button to change the languages.
How it works:
- With a Tellu user: each phone turns its owner's speech into text and sends it, and the other phone translates it.
- It turns on for both of you: in a call between two Tellu users, when one of you turns on translation, it turns on automatically on the other phone too — once per call, and not if that person turned it off themselves. They see a short notice and can stop it at any time by tapping Translate.
- With a regular phone number: your phone listens to the other person and translates them for you; that's why you need to choose their language.
- Text translation only — no translated voice is played.
Cost: free.
