Japanese to English Live Translated Captions
Japanese presentations captioned live in English, so global teams join the discussion in real time.
A Japanese speaker presents while the global team sits in — and the translated deck always arrives a step late. Avoce turns Japanese speech into live English captions, so international colleagues ask questions and weigh in on the spot. When the talk ends, the English transcript is already done.
Nothing to install — it runs in the browser. Capture a live talk with the microphone, or caption an online meeting or video through tab audio. Register names and jargon in the glossary so the English stays exact, let the audience scan a QR code to read captions on their own phones, and export the transcript as txt, Markdown, or srt when you’re done.
Where it shines
- Japanese tech talks
- Japanese speakers at global events
- Reports from Japan-side teams
What to watch for in this direction
A dropped subject has to be supplied
Japanese can leave the subject out entirely; English cannot. Does 来週リリースします mean we ship next week, or they do? The model infers it from earlier context. In meetings where several people speak in turn, this is the largest single source of error — occasionally naming the subject aloud changes the result noticeably.
Indirect phrasing loses its meaning in English
ちょっと難しいですね literally reads “that’s a little difficult” and usually means no. Rendered literally, an English-speaking listener hears room to negotiate. This is a cultural gap rather than a translation error, so have a person confirm the conclusion in a negotiation that matters.
Counting by 万 versus by thousand
Japanese counts in units of 万 (ten thousand); English steps by thousand and million. 3億5000万 has to become 350 million. Numbers are the least forgiving part of any translation, so leave the original line visible and let the audience check the digits themselves.
Three steps to start — nothing to install.
Put these in the glossary first
The glossary applies to both recognition and translation: terms you register up front stop the model re-guessing a rendering every time.
- Official English names for the company and its departments
- Model numbers and product names, so they are not paraphrased
- How to render business terms with no English equivalent (稟議, 根回し)
- Romanised spellings of the speakers’ names
One point buys one minute of live translation — about $3.70 an hour on the $10.99 / 180-point pack. Signing up gets you a free 20-minute trial, no credit card needed.
Common questions
How does keigo come out in English?
English has no matching hierarchy, so the output is ordinary business English. Fine gradations of politeness flatten out, which is acceptable in most settings.
Is it suitable for a technical talk?
Yes, provided the terminology goes into the glossary first. Model numbers, function names, and internal code names become harder to follow, not easier, once they are paraphrased.
Do I get an English transcript afterwards?
Yes — export as txt, Markdown, or timestamped srt when the session ends.
