Event replay captions, audio and speaker review: a practical guide Review automatic captions against the final recording and audio, then check speaker labels, meaningful sounds and playback in the release player. Author: EVENTODIT Editorial Team Published: 2026-10-28T00:09:59.179875Z Updated: 2026-10-31T11:07:15+09:00 Original URL: https://eventodit.com/en/stories/event-recorded-video-caption-audio-speaker-review.html Practical summary Key decision: Review the final edit against caption content, speakers, necessary sounds and timing before publication. Responsible roles / intended readers: Event video producers, publishing leads and accessibility reviewers Record / next task: Video and caption versions, review environment, error segments and confirmation after correction Basis of information: Direct review of the W3C WCAG 2.2 prerecorded captions criterion, caption production guidance and draft initial checks. Review sequence and records are editorial applications. Editorial review: 2026-10-28 Part 1. Planning and content lead "Do not approve automatic captions without checking the source version and the separate need for visual description." - Review the W3C prerecorded-caption criterion and its exception: WCAG 2.2 Success Criterion 1.2.2 requires captions for prerecorded audio content in synchronized media, except when the media provides no more information than the text and is clearly labelled as a media alternative for that text. Captions convey audio information needed to understand the programme in time with the video. Check the scope and exception in advance; this does not determine a Korean legal obligation for every event recording. - Do not approve automatic captions without review: A visible track generated by a platform or automatic speech recognition tool does not establish accuracy. Require a reviewer to compare it with the original audio and make corrections before approval. - Assess audio description and alternatives separately: Captions conveying speech and sound do not necessarily describe charts or information available only on screen. Review and approve any need for audio description or an alternative separately from caption review. - Record the review environment and history: Keep video and caption versions, the review environment, error timecodes and the results of rechecking corrections together in an approval record for handover and traceability. - Manage the three-step review: The video owner confirms the final video used to create the captions; the reviewer checks speech, speakers, sounds and timing; and the publisher tests caption selection and corrected segments in the release player. Part 2. Caption production and content review "Match the caption source to the final edit and identify speakers and essential non-speech sounds." - Match the final edit and caption source: After a presentation is reordered or footage is cut, an older caption file can contain the correct words at the wrong time. Obtain and compare the final video filename, approval time and source version used for the caption file. - Identify speaker changes and off-screen speakers: Add labels where a speaker changes or an off-screen question makes it difficult to tell who is speaking. Record the segment timecodes and identify the speaker clearly. - Include non-speech sounds needed for understanding: There is no need to list every background sound. Agree with the caption producer on appropriate wording and placement for applause, alarms, effects or other non-speech audio needed to understand the programme, as described in W3C guidance. - Check numbers, names and negative statements against the audio: Compare statistics, speaker names, technical names and positive or negative expressions with the original speech. Record the person who checked the source and the corrected version. - Prevent captions from covering important material: Check whether a caption box obscures key slide text, figures or a speaker nameplate. Reposition captions where needed and record the corrected screen. | Where to check | What to verify | What to record after correction | | --- | --- | --- | | Speaker changes and off-camera questions | Can the viewer identify the speaker? | Segment and speaker label | | Alarm or other meaningful effect | Is the necessary sound conveyed? | Wording and location | | Numbers, names and negative statements | Do the words match the actual speech? | Reviewer and corrected version | | Captions and visual information | Do captions cover important text or material? | Screen after repositioning | This table is EVENTODIT’s proposed application of the W3C guidance to event-video review. Part 3. Publishing and player review "Do not stop at the editor. Play the recording from beginning to end in the release player and check synchronization." - Review playback in the actual release player: Do not check only a text document or editing preview. Enable captions in the player intended for public release and review them alongside the video. - Check critical synchronization points: Pay particular attention to speaker changes, edit cuts, and the beginning and end of the video, comparing captions with the actual audio. - Test closed-caption and language controls: If viewers can enable and disable captions, use ordinary viewer access to test the controls and select the intended language track. - Assign a full-review owner and return errors with timecodes: Designate someone to review accuracy from beginning to end. Return problems to the producer with the precise video timecode. - Replace revised files and recheck changes before release: If the recording or captions are modified, replace the final platform files and verify the affected segments again in the actual player before approving publication. Practical workflow · Sequence Review the source, captions and final player 1. Confirm final cut The video owner identifies the version used to create captions. 2. Review caption content The reviewer checks speech, speakers, necessary sounds and timing. 3. Check final playback The publisher tests caption selection and corrected segments in the release player. Note: EVENTODIT application. Assess audio description of visual information separately. Use the original records and supporting templates Keep the video team’s final video/caption version list and timecoded feedback register. Record source speech, speaker and essential sounds, numbers/names, caption placement/synchronisation, corrections and recheck owner for each affected segment; also test captions and language selection in the actual public player. The [media handover and playback record](/en/templates/video-handover.html) supports final filenames/versions, actual picture/audio playback and revised-file handover. Full caption review remains in the timecoded register; recording file receipt alone does not complete it. **Final check before use:** Before publishing the replay and captions on the official platform, cross-check the final versions, speaker and necessary-sound labels, and playback in the release player. Application conditions For checking captions of speech and meaningful audio in prerecorded event videos. Assess audio description of visual information separately. Unconfirmed information No specific video, platform or device was tested, and overall accessibility conformance was not assessed. Korean legal applicability requires separate review.
