A transcript presents the spoken content as a readable document, while subtitles appear at timed points during video. A transcript can help review information but does not provide the same synchronized viewing experience. Availability and accuracy depend on the supplied material. Choose according to the task: a transcript supports reading and searching the content as a document, while synchronized captions support following the programme at its current point. Accessibility may require speaker labels and meaningful sounds in either form, depending on the content.
Check purpose
Reading later and following live dialogue are different needs. A viewer following fast dialogue needs text synchronized with the picture, whereas someone reviewing a lecture may prefer a readable transcript with paragraphs or timestamps. One format does not automatically replace the other. Check whether the player offers captions and whether a separate transcript is actually supplied, rather than assuming a subtitle button implies an exportable document. For your own material, decide who will use the text before choosing how it should be presented.
Keep sound information
Accessible transcripts may include meaningful non-speech details. An accessible text alternative may need speaker identification, meaningful non-speech sound and, where appropriate, visual information needed to understand the content. A dialogue-only extract can omit context that a reader or viewer relies on. Check a representative section with an off-screen sound or a speaker change rather than judging only word count. Captions and transcripts can share wording while still requiring different timing, formatting or descriptive decisions for their intended use.
Avoid accuracy assumptions
Automatically produced text can contain errors. Automatically generated text can misrecognize names, numbers and overlapping voices, so review important passages against the authorized source. A transcript presented as a summary should be labeled accordingly because it changes the level of detail. Do not assume that an app exposing captions permits public redistribution or automatically publishes a transcript. If creating text from your own content, preserve useful timestamps and make corrections without falsely claiming the result is a verbatim or professionally verified record.

An example to work through
A tutorial transcript supports searching a topic, while captions help follow the same explanation during playback. A student can search a lecture transcript for a term later, while timed captions help them follow that same sentence during playback. The two uses benefit from different presentation, and a raw uncorrected speech-recognition dump may miss both the correct terminology and a meaningful speaker change.
Questions about this topic
Are transcripts always word-perfect?
No. Accuracy depends on the source and review process, including how names and unclear speech are handled.
Do captions automatically create a public transcript?
Not in every system. Availability, export and publication are separate capabilities that need checking in the actual system.
