- Output
Download SRT subtitles for a player or editor, or JSON with structured text and timestamps. The tool creates separate files; it does not burn captions into a video. Review and edit the transcript in your usual subtitle editor.
- What to check
Enable speaker labels to request a distinction between voices. Labels such as speaker_0 may be returned when available; they do not identify real people and may be incomplete or incorrect.
Noise, overlapping speakers, accents and unclear speech can cause missing or incorrect words. Check names, numbers and timings against the recording, then correct the downloaded file in a subtitle or text editor.
