Multilingual Options for Small Conferences, by Budget

What can a small conference do at each budget level?

Here's the overview. As budget goes up, so does accuracy — and so does how little organizing you have to do yourself. At the low end, most of the work falls on the organizer and the speaker, ahead of the event. At the high end, a hired team handles the language work in real time, and the organizer mainly needs to book them early and share materials in advance.

It helps to think in terms of what a given budget actually buys, rather than treating "translation" as one single line item. A conference that mixes tiers — say, human interpretation for the keynote and an AI live translation service for breakout sessions — often gets better results per yen than putting the whole budget into one option.

What ¥0 gets you

Money isn't the only lever — preparation is. The easiest step is asking speakers to add English text to their slides alongside the original language. If handouts exist, translating even the key pages ahead of time helps, and a one-page glossary of technical terms and product names can go a long way for attendees who are relying on their own translation apps during the talk.

You can also just tell attendees up front to use a translation app on their own phones, and share the agenda and any acronyms in advance so their apps have less to guess at. These are real options, but they're supplements, not solutions. None of them capture what's actually said in real time, and Q&A stays just as hard to follow — a live back-and-forth is exactly where pre-translated materials run out of usefulness.

What a few thousand to tens of thousands of yen gets you

This is where AI live translation services enter the picture. They translate a speaker's audio as they talk, and attendees receive captions or translated audio on their own phones — no receivers to hand out or collect, and no separate app for attendees to install. Most bill in short sessions, so a single-talk booking is realistic even for a first-time organizer testing the idea.

Stretch the budget into the tens of thousands of yen and a freelance consecutive interpreter becomes possible for a spot booking. Keep in mind that consecutive interpretation pauses after each sentence or two, which stretches the talk's actual running time — it fits breakout sessions with room to spare better than a tightly scheduled main track. It's also worth asking any freelance interpreter about minimum booking length, since even a short spot booking can run into the same half-day minimums that larger interpreting agencies apply.

Hundreds of thousands of yen: bringing in human simultaneous interpreters

If accuracy comes first, human simultaneous interpretation is still the most reliable option — but it isn't cheap. Published rates from interpreting agencies put a standard-tier interpreter at roughly ¥50,000–¥70,000 for a half day[1]. Because simultaneous interpretation is typically staffed with at least two interpreters[1], that half-day figure usually doubles to around ¥120,000–¥150,000 before equipment.

A rate guide from OCiETe puts specialized dispatched interpreters at roughly ¥65,000–¥70,000 for a half day and ¥90,000+ for a full day[2]. With a budget this size, you can cover a keynote or an entire internationally focused conference with human interpreters — though it's a heavier investment than most technical meetups of a few dozen people need.

Summary: choose by budget and purpose

There's no single right answer for making a small conference multilingual. The right tool depends on your budget and how much accuracy the moment demands.

• ¥0: Widen coverage with translated handouts and bilingual slides
• A few thousand yen: Start real-time coverage with an AI live translation service
• Tens of thousands of yen: Book a consecutive interpreter for a breakout session
• Hundreds of thousands of yen+: Bring in human simultaneous interpreters for keynotes or the whole event

VoxFlight: an option for small conferences

VoxFlight is a live translation service built for small in-person events. The organizer starts a session from an iPhone and displays a QR code in the room. Attendees scan it with their phone's browser, pick their language, and receive translated captions and translated audio. No app install or account is required.

Audio comes from the iPhone's built-in microphone or an external microphone connected to it. VoxFlight does not persist original or translated audio in its managed databases or storage; external AI provider processing and retention terms are disclosed in the Privacy Policy. Pricing shown below is planned pricing ahead of general availability. Once paid purchase is available, the App Store processes payment when a session pass is purchased; the purchased pass is consumed when translation starts.

For two target languages, the complete two-language pass is purchased once in the App Store for the same duration and attendee limit. It is not an add-on after buying a one-language pass, and the total is shown before purchase.

VoxFlight is currently in pre-launch preparation. Prices above are planned pricing, and a waitlist is open now.

VoxFlight isn't the right fit for every case. Medical or legal interpretation, where errors aren't acceptable; large conferences that build a dedicated interpreter team; and panel discussions where multiple people speak at once are all better served by human interpretation, even at a higher budget. For organizers weighing a few thousand to tens of thousands of yen for a small conference, though, it's a realistic option.
