Create subtitles from speech

Transcribe your recording, check the wording and timing, then choose an export. Transcript export formats: PDF, DOCX, TXT, SRT and VTT. Review names, overlapping speech and punctuation before publishing captions. To check an exported file rather than the transcript, the subtitle quality checker reports invalid or overlapping timings, reading speed and line length.
