Make readable SRT captions from a spoken recording

A step-by-step guide to turning automatic transcription into timed captions that viewers can actually follow.

The first transcription is only a starting point. Good captions need accurate words, correct timing and sensible line breaks. They should describe what is heard rather than silently changing the speaker’s meaning.

Prepare speech for recognition

Choose a recording in which voices are clear and speech is not buried beneath music. Check that the file plays end to end before starting a model download or transcription pass.

Model processing can take longer on small devices. If your browser runs out of memory, try shorter segments or a more compact model where the interface allows it.

Review each caption against playback

Correct names, specialist terms and ambiguous numbers manually. Watch for invented words during pauses and for captions that run across changes of speaker. Automatic tools can miss hesitations or punctuation that meaningfully changes a sentence.

Keep captions readable by using natural phrase boundaries and avoiding excessive text in a single cue. Use the playback timeline to adjust cues that appear too early or linger after the speaker stops.

Export and test SRT

An SRT file contains numbered cues, time ranges and text. Import it into the intended video editor or player to confirm the timeline format and character encoding are accepted.

Keep a plain-text transcript as well when you need to search, edit or publish a companion article. Verify that you have permission to publish both the recording and its transcript.
