Set it up in 30 seconds
Two speakers, one phone - no tapping between sentences.
Choose VI on one speaker, JA on the other. You do this once per conversation.
Speak naturally. The app notices which side is talking and flips direction itself.
The other person reads the bilingual screen, or taps a line to hear it spoken.
Live bilingual captions as people talk, plus a saved transcript you can edit.

Vietnamese and Japanese: two different manners
What the translation engine actually watches between these two languages.
Vietnamese sets politeness with a word at the end of the sentence, while Japanese switches into a whole separate keigo form - so the same thank-you is rebuilt, not word-swapped.
Vietnamese asks with a question word inside the sentence and Japanese with a か ending - the same question is reassembled in the other order.
Spoken Vietnamese runs together, but the engine splits it into words first - so the transcript shows the same sentence spaced and readable.
Why it beats tapping a translation box
Same appointment, same menu - but nobody types and nobody waits for a turn to pass.
Set once, then the app follows whoever speaks. Direction is decided by the voice, not by a button.
Each line shows as it is spoken and stays in the transcript, ready to edit, copy or share after.
Tap a line on the screen and the phone reads it, so the other side hears their own language too.
What it does - and what it doesn't
Straight answers beat surprises: the boundaries here are the real app's boundaries.
Try this: Read the text out loud - Felo translates the sound instead.
Try this: Keep the app open on Wi-Fi or a data plan.
Try this: Press the mic and speak; text stays for reviewing the transcript.

Frequently asked questions
Is Felo's Vietnamese to Japanese translator free?
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.
Can it translate Vietnamese to Japanese and back for both parties?
Yes. Pick Vietnamese on one speaker and Japanese 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.
Does it keep the polite ạ or dạ and the keigo on either side?
The engine is trained on spoken Vietnamese and Japanese, so a speaker who uses ạ or dạ usually gets a matching polite register, and service keigo stays polite. If a line comes out more casual than you meant, re-speak it slowly and check the transcript.
Can a Vietnamese traveler use it at a hotel in Japan?
Yes - check-in, breakfast times and shop exchanges are typical scenes. Say a line in Vietnamese and the staff hears it in Japanese; their reply shows under it in Vietnamese, ready to show on the screen.
Does it handle Northern and Southern Vietnamese accents?
Standard Vietnamese works best. It is trained on spoken Vietnamese, so everyday speech usually comes out fine; a heavy regional accent that strays far from standard spelling can come out more literally. Re-speak the line and check the transcript.
Does Felo need the internet for live translation?
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.
Can it read a Japanese sign or menu with the camera?
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.
How is this different from pasting into a Vietnamese-Japanese web translator?
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.
Can I use it on a phone call?
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.
