Vietnamese to English translation, both ways, by voice.

Yes, Felo is free to try on iOS and Android, rated 4.4 out of 5 on the App Store from 60 reviews. Longer conversations come from time-based plans, such as a 2-hour plan valid for 30 days.

Yes. Pick Vietnamese on one speaker and English on the other; Felo translates each sentence into the other language as it is spoken, and one phone keeps the whole two-direction exchange in order.

The engine is trained on spoken Vietnamese and English, so the address form you choose for the other person usually carries the same closeness, and the English side stays natural. If a line feels more formal or more casual than you meant, re-speak it and check the transcript.

Yes - check-in, pharmacy stops and clinic appointments are typical scenes. Say a line in Vietnamese and the staff hears it in English; their reply comes back under it in Vietnamese, ready to show on the screen.

Standard Vietnamese and standard English work best, since the engine is trained on everyday speech in both. A heavy accent in either language can come out more literally - re-speak the line a little slower and check the transcript.

Yes. Live voice translation runs over the network, so keep a stable connection - there are no offline packs. Set both languages before you arrive and the first conversation is ready.

No. Felo is a voice translator - it translates what people say, not printed text. If a menu is on the table, read the dish aloud and Felo will translate it for you.

A web translator needs both people to type, sentence by sentence. Felo listens as each person speaks, translates it, and keeps an editable transcript - so one phone is all two sides need to talk.

Keep the call on speaker and place the phone nearby - Felo translates what the microphone hears. It does not sit inside the system call, so voices sent through earphones are not translated.
