Subtitle Generator — Create SRT & VTT Captions

Generate accurate SRT and VTT subtitles from any audio or video. AuTrans's subtitle generator is tuned for Nigerian English, Pidgin, Yoruba, Hausa and Igbo — captions that actually match how people speak.

Auto-caption tools built for American English mangle Nigerian speech — misspelling names, flattening Pidgin, and butchering anything with an accent. AuTrans's subtitle generator creates properly-timed SRT and VTT captions from your audio or video, tuned for Nigerian English, Pidgin, Yoruba, Hausa and Igbo, and it keeps the code-switching intact instead of guessing wrong. Upload your file, get a speaker-labelled transcript you can quickly edit, and export clean subtitle files with correct line-wrapping and timing — ready for YouTube, Nollywood releases, church livestreams or social clips. It's captioning that respects the language your audience actually speaks.

Frequently asked questions

How do I generate subtitles for a video?

Upload the video (or its audio) to AuTrans. It transcribes the speech, lets you edit the text, and exports timed SRT or VTT subtitle files ready to load into your video editor or upload to YouTube.

What's the difference between SRT and VTT?

Both are subtitle formats. SRT is the most widely supported (YouTube, most editors); VTT (WebVTT) is the web-native format with styling support. AuTrans exports both from the same transcript.

Can it caption Pidgin, Yoruba, Hausa or Igbo video?

Yes. AuTrans is tuned for Nigerian languages and code-switching, so captions match what's actually said instead of forcing everything into standard English like generic auto-caption tools.

Are the subtitle timings accurate?

Yes — captions are generated from word-level timestamps, so they line up with the audio. You can fine-tune the transcript before export if you want exact phrasing.

Can I edit the captions before exporting?

Yes. You edit the transcript in AuTrans first — fix words, rename speakers, add vocabulary — then export clean SRT/VTT that reflect your edits.
