START HERE
Run a complete rehearsal using production microphones, mixer, network, screens and audience phones. Assign owners for audio, caption corrections, broadcast and audience support, then record observations. One caption on a demo laptop does not validate the venue chain.
Use the actual signal chain
Confirm that the production microphone and mixer output reach recognition. Listen for feedback, music or sound from another room. If recording a sample for review, establish participant permission and the applicable handling requirements first.
Include names, organisations, numbers, terminology, pauses and natural speech. Give the operator approved terms before comparing audio with captions. A short greeting alone cannot exercise the difficult parts of a real talk.
Inspect four destinations
On the operator console, inspect source, translation and corrections. On the venue screen, test readability from the back. At the broadcast desk, check placement, background and aspect ratio. On audience phones, check the QR entry, language selection and steps to start listening.
Listen to translated speech with headphones; a playback icon is not evidence of audible output. Follow a long sentence with a short one and check order, complete endings and behaviour after a pause. Network conditions, phone settings and browser playback restrictions affect the experience.
Rehearse state changes and support
Check whether the waiting, paused and ended pages explain the state clearly. Prepare instructions covering the QR code, language choice, headphones and where to get help, so every viewer does not need a verbal explanation.
An authorised operator should test pause and recovery under an agreed plan. Do not experiment during the live event. When a connection fails, identify whether audio, networking, room state or equipment is responsible before several people change settings simultaneously.
Create a usable handover
Record time, equipment, languages, room, destinations and observations. Each issue should state reproduction steps, impact and owner. Separate fixed-and-retested items from planned actions; do not replace evidence with zero-failure or zero-latency claims.
Before opening, recheck the final agenda and glossary version and hand over controls and contacts. AI interpretation can aid understanding, while important negotiations, legal commitments and other high-stakes material require language support appropriate to the situation.
A practical comparison
| Owner | Acceptance | Record |
|---|---|---|
| Audio | Production microphone, routing, monitoring | Source and observed faults |
| Captions | Names, numbers, corrections | Samples and issue locations |
| Broadcast | Aspect ratio, placement, transitions | Actual programme picture |
| Audience support | QR access, language, headphones | Device and reproduction steps |
Before you sign off
- Use production inputs and intended displays.
- Validate audience captions and speech separately.
- Have an authorised operator rehearse recovery and assign issue owners.
- Hand over final terminology, agenda and audience instructions.
Frequently asked questions
Does connectivity mean the rehearsal passed?
No. Check actual audio, language content, readability, speech playback and operator actions as well.
Can a live event be guaranteed to have no delay?
No. Audio, networking, recognition, translation, synthesis and playback all take time. Observe the real venue and agree on acceptable behaviour.
