1. Make responsibilities explicit

A working keynote does not verify another room or a remote speaker. Complete one sheet per distinct delivery path. Confirm the support arrangement with the attendee or responsible access lead; a technical operator should not decide an accommodation while repairing a microphone.

Planner and delivery responsibility matrix
Owner Decision / evidence required Named person and backup
Producer Programme, resources and authority to pause
Access lead Requested support and an agreed alternative
AV lead Microphones, outgoing feed, room/session mapping
Caption provider / reviewer Language, terminology and text quality checks
Audience support Joining, device check and feedback route

2. Trace source → text → audience

Use a distinctive sentence containing a name, a number and a negative, then an ordinary question. Keep the expected words in the rehearsal brief. An input meter, a readable preview and an attendee’s successful task are separate observations.

Observe the whole path
Checkpoint Try this Observed result / next action
Source Speak at the lectern, handheld and remote microphone; include relevant playback.
Text Read the received captions; check meaning, names, numbers and “not”.
Audience Open the intended session on a separate device; check reading, joining and asking a question.
Transition Move to the next room/session and confirm the source belongs there.

3. Record latency without promising a universal threshold

Measure the path the audience will use. Record a source cue and when that cue is heard or displayed at the attendee endpoint, with the clock or recording method. A connection gauge is not the same as end-to-end delay. Keep floor audio, captions, translated text and interpreted speech as separate routes.

Delay observation log — no target is pre-filled
Route / device / conditions Source cue and received cue times Method / observed delay / task impact

For example, a tester may record the source and attendee display together, identify the same cue in that recording and note the difference. Write down limitations of the method. Do not compare timestamps from unsynchronized devices as if they were precise. Repeat under representative room and network conditions and ask whether the observed behavior supports the actual participation task.

4. Practise a fallback before opening doors

Name the person who can pause or alter the programme. Agree what attendees will be told and where they can obtain help. A transcript tomorrow does not replace live participation today. Do not silently swap captioning for another format without discussing the person’s needs.

5. Ask for useful feedback

“Were you able to follow the parts you needed? Where did the text or joining route make that difficult? Was there a point when you could not ask or respond? What change would help next time?”

Offer a private, usable feedback route. Record the issue and task impact without collecting unnecessary personal information. Distinguish “the captions appeared” from “the attendee could complete the activity.” A successful rehearsal is evidence about that tested arrangement, not a compliance certificate or a guarantee for every session.
