Good live captions start with good preparation. This checklist is organized by role. Start reading it a week before the event, and run the rehearsal in the last section just before you open.
Organizers: one week before
- Check your hours: the organization needs more than 10 minutes left when recording starts. The event page shows about how much recording time this event has left. Each extra translation language uses 10% more hours, so estimate by the number of languages.
- Fill in the event topic and background: write the field, the speakers and the terms that come up often. Translation gets more accurate.
- Choose only the languages the speaker really uses: the right choice improves recognition; too many languages slow it down.
- Choose translation languages and the listener cap: the default cap is 500. When the cap is reached, new listeners are told the event is full.
- Set a listener password if you need one: listeners enter it the first time they open the page. The password shows only once when you set it, so write it down.
- Prepare glossaries: add speaker names, organizations, products and terms to a glossary, then add the glossary in the event's "Glossaries" tab. See the glossary guide.
- Check the advanced settings: for a panel with several speakers, turn on "Will several speakers take turns". To let listeners hear speech, turn on "Listeners can hear voice".
The speaker link
- A speaker link is valid for 7 days after it is created. If the event is more than a week away, click "Regenerate speaker link" on the event page shortly before the event, then send the new link.
- Click "Copy instructions for the speaker" to paste the link and the steps into an email or a chat message.
- The speaker link only shows on the computer that created the event. Send it to the speaker or save it yourself.
Speakers: before the talk
- Open the speaker link in Chrome or Edge on a computer. A phone also works, but its screen must stay on.
- When the browser asks for the microphone, click "Allow". If the link opens inside an app such as LINE or Facebook, open it in Chrome or Safari instead.
- In the settings panel, choose the audio source and check that the level meter moves. If no sound arrives for 6 seconds, the page asks you to check the microphone.
- Close programs that can hold the microphone, such as video meetings.
- In "Languages I speak", choose the language of your talk.
- To caption a video or a remote speaker, use "Share a tab's audio" (desktop Chrome).
See audio tips for more.
Venue projector and live stream
- In the event's "Projector captions" tab, set up as many caption sets as you need. Each set has its own URL, with its own languages, font size and position for a different screen.
- Open the projector URL on the computer connected to the projector and choose a mode: full screen, picture-in-picture (on top of your slides), or capture slides and compose.
- For a live stream, add a "Browser source" in OBS or vMix with the broadcast URL, size 1920×1080.
- Click "Send test captions": every screen with that URL open shows sample captions for 30 seconds, so you can check position and size before you open.
- "Fade out after" keeps the last caption from staying on screen during breaks.
See display and OBS for details.
Listener entry points
- Print the listener QR code from the event page on table cards, posters or your opening slide.
- "Let listeners join" on the speaker page also shows the QR code full screen, which works well at the start.
- If there is a listener password, announce it in the venue. The same device skips the password for 7 days.
- Tell listeners to use headphones for speech, and to add the page to their home screen so the screen is less likely to turn off.
- If the venue Wi-Fi needs a sign-in page, listeners may not connect. They can switch to mobile data.
15 minutes before: rehearsal
- The speaker clicks "Start", says a few sentences, and checks that captions appear on the speaker page.
- Scan the QR code with one phone, pick a language, and check that captions appear on the listener page.
- Check the caption position on the projector or stream.
- After the rehearsal, the speaker clicks "Clear captions". Captions on every screen clear; the transcript stays.
Rehearsal recording also counts toward your hours, so plan for it.
After the event
- Click "End event" on the event page. Captions and transcripts stay, and you can reopen the event at any time.
- Download the transcript as CSV or JSON in the "Transcript" tab.
- Open "Usage reports" to see the recording time and hours used for each session, and export them as CSV.
