Captioning terminology guide
Live transcription converts speech into a running text record. Live captioning presents synchronized, readable text with the media or event and should convey relevant speaker changes and meaningful sounds for the intended audience. The same speech-recognition or human-captioning source can contribute to both, but an unformatted transcript is not automatically an accessible live-caption experience.

What it is
The terms are often used interchangeably in product menus and billing, but the audience outcome matters more than the label. A transcript can support notes, search, review, or post-event editing. Captions must be timed, segmented, displayed, and monitored where the audience is watching. A production may need personal browser captions, shared-screen text, open broadcast graphics, selectable closed captions, and a separate transcript artifact.
Capabilities and outputs
The exact configuration depends on the event, audience destination, enabled features, and downstream production equipment.
| Capability | What it means in production |
|---|---|
| Live transcription | Creates a running text representation of speech that may be used for notes, search, review, editing, or as an upstream text source. |
| Live captions | Present synchronized text in readable caption frames or rolling lines at the time the audience receives the associated audio or media. |
| Accessibility information | Captions can identify speakers and convey meaningful non-speech audio that a word-only transcript may omit. |
| Audience destinations | Caption text can reach personal browsers, room displays, graphics layers, or embedded closed-caption services through different production paths. |
| Post-event record | A saved transcript or caption file is a separate deliverable whose format, editing, speaker labels, timing data, and retention should be specified. |
Production workflow
Decide whether people need synchronized live access, a separate running text stream, searchable notes, a post-event record, or several outputs.
Document words, punctuation, speaker identity, meaningful sounds, timing, line length, display behavior, language, and review expectations.
Configure personal viewers, room displays, graphics, embedded caption services, and stored artifacts separately.
Evaluate representative speech, timing, readability, speaker changes, sounds, devices, screens, and downstream media systems.
Questions buyers and producers ask
No. Transcription creates text from speech. Captioning turns that text into an audience-facing, synchronized experience and may also need speaker identification, meaningful sounds, readable segmentation, placement, and display controls.
Use live captions when the audience needs synchronized access while the program is happening. Add a transcript when the event also needs a searchable or editable text record. Many professional productions need both, with separately defined outputs.
Accessibility captions should convey meaningful audio information, including relevant speaker identification, music, sound effects, or audience reaction when that information is needed to understand the program.
It can be an upstream source, but the production still needs suitable timing, segmentation, readability, speaker and sound handling, monitoring, audience delivery, and fallback. Raw text alone does not prove an accessible result.
No. Open captions are visible in the program picture or graphics layer. Closed captions are data a compatible viewer can enable. Both may begin with transcribed speech, but each requires a distinct presentation and delivery path.
4ALL LIVE can route a configured caption stream to audience browsers, QR-code viewers, shared displays, browser-source overlays, Ross XPression graphics, or supported CEA-608/708 Encoder workflows. Each endpoint is configured and tested separately.
