Japanese to English translation, both ways, by voice.
Speak Japanese and watch the English appear - or answer in English and hear Japanese - every line open and saved for later.
Set it up in 30 seconds
Two speakers, one phone - no tapping between sentences.
Choose JA on one speaker, EN 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.
Conversations for Japanese and English, ready to go
Real check-in, taxi and sightseeing lines - copy the flow, or just let the app speak.
Japanese frames, English straight lines
What the translation engine actually watches between these two languages.
'I'd like to check in' becomes お願いします at the front desk - the request frame carries the courtesy.
ご案内いたします stays polite out loud but comes out as a plain English offer. No word-for-word keigo.
A polite English request maps to おっしゃっていただけますか - the apology frame, not the literal words.
Why it beats tapping a translation box
Same flight, same desk - 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.
At a glance
Straight from the App Store
Real reviews from live two-way conversations. Names kept as posted.
“I use it to study English - checking my pronunciation with it. When I don't know how to say something in English, I speak Japanese and the app shows it in English. It's a great way to learn.”
“Very few apps translate in real time; of those, this one runs smoothly. I keep it on my phone.”
Frequently asked questions
Is Felo's Japanese to English translator free?
Yes, Felo is free to try on iOS and Android and holds a 4.4 out of 5 rating on the App Store based on 60 reviews. Longer sessions come from time-based plans, such as a 2-hour plan valid for 30 days.
Can it translate English to Japanese as well?
Yes, both directions. Pick the language per speaker - one side English, one side Japanese - and Felo translates each sentence into the other immediately, so a tourist and a hotel desk can talk without an interpreter.
Does Felo mix up keigo and casual Japanese?
In most cases no. It is trained on spoken Japanese, so polite telephone and service Japanese stays polite, while casual chats stay casual. Rare regional dialects may come out with less consistency.
How fast is the translation in a conversation?
Each phrase is translated as it is finished, then shown and read aloud, so the reply follows within a breath or two. Speaking one at a time keeps the conversation natural.
Can I use it to improve my English pronunciation?
Many learners do. Speak English into the app and the transcript appears in English along with the Japanese, so you can compare what you said with what you meant, and re-read it aloud yourself.
Is an internet connection required?
Yes, live translation runs over the network. There are no offline packs, so keep a connection - or use Wi-Fi - while you talk.
Can it help an English-speaking guest order at a restaurant?
Yes. Read the dish aloud in English (or let the guest say it) and the staff hears it in Japanese; the staff answers in Japanese and the guest hears English. Common ordering lines are in the scene tabs on this page.
What about formal business Japanese vs casual English?
The speaker's register is generally kept: polite service Japanese stays polite, and the English output lands in a matching level of formality instead of being flattened into one fixed style.
Will it work in a noisy restaurant or train station?
It works best when the phone is close and people take turns. Noise windows between sentences help; if it picks up the wrong source, speak louder and slower, and check the transcript.
