Audio to SRT

Select a local media file to preview and generate subtitles.

Settings

Auto-detect is the default. Select a language if detection is inaccurate.

Standard is faster and uses less memory. Enhanced may improve recognition but needs a larger download, more memory and more time.

Leave the end blank to process to the end. Regenerating a range replaces overlapping cues and keeps the others.

Embedded tracks

Generate subtitles from speech in your local media file. Once complete, captions follow playback.

Subtitle file

Import SRT or VTT up to 50 MB. All cues are kept.

Media files are processed in your browser and are not uploaded to a server.

The subtitles use the original audio timeline. You can recognize the whole recording or a selected range; the audio file itself stays unchanged.

How to convert audio to SRT

  1. Select an audio file. Choose the spoken language or use automatic detection.
  2. Generate subtitles and listen to the recording to review text and timing.
  3. Click Export SRT, or Export VTT when you need WebVTT.

Subtitle Generator FAQ

How do I make SRT from MP3?

Select the MP3 file, generate subtitles and review the result. Export SRT saves the text with start and end times.

Does this change my audio file?

No. The downloaded SRT is a separate text file. Recognition and editing happen in your browser.

Can I redo only part of a recording?

Set start and end seconds in Settings. New subtitles keep the original timeline and replace overlapping cues; subtitles outside the range remain.
