How to generate SRT subtitles

01
Upload audio or video Any format — drop the file or paste a link.
02
It transcribes and times Speech is transcribed and split into properly-timed caption cues.
03
Download SRT (and VTT) Both subtitle formats from one job, plus the full transcript.

Most social video is watched on mute, captioned video gets watched longer, and accessibility rules increasingly require subtitles outright. An SRT subtitle generator turns the spoken audio into a timed caption file without you typing a single timestamp.

Upload the video or audio and Vocce transcribes it, then breaks the text into cues with accurate in/out times and a comfortable reading speed. Long files stay in sync because the timestamps come straight from the recognition engine, not a guess.

You get an SRT and a VTT from the same job — ready to upload to YouTube, drop into Premiere or CapCut, or attach to an HTML5 player. Low-confidence lines are flagged so you only review what actually needs it.

// features

Built to survive real files.

Properly-timed cues

Captions are split for readable line length and reading speed, not dumped as one long block.

SRT and VTT together

One job emits both formats plus the transcript — there's no second export to run.

Accurate on long files

Timestamps come from the engine and stay in sync across multi-hour videos.

Review only what's shaky

Low-confidence lines are flagged, so you fix the few that matter instead of proofing everything.

Translate next

Pair it with the Subtitle Translator to localize the captions while keeping the timeline intact.

Over 100 languages

Caption talks in any major language, detected automatically.

Accessibility compliance

Generate SRT/VTT for courses, products, and public content that needs captions to meet accessibility requirements.

Video editors

Skip manual caption typing — import a generated SRT into Premiere, Resolve, or CapCut and just fine-tune.

Subtitle Generator, answered.

How do I generate an SRT file from a video? +

Upload audio or video above and choose subtitles. Vocce transcribes the speech and emits SRT and VTT files with accurate timestamps, plus the full transcript.

What's the difference between SRT and VTT? +

SRT is the classic format most editors and players accept; VTT is the web-native flavor used by HTML5 video. Vocce exports both from the same job.

Are the subtitle timestamps accurate? +

Yes — timestamps come straight from the recognition engine, and long files are stitched without drift. Low-confidence lines are flagged so you can review just those.

Can I translate the subtitles afterwards? +

Yes — pair this with the Subtitle Translator tool to localize SRT/VTT files while keeping the original timeline intact.
