How do I generate Thai subtitles?

Pepys builds Thai subtitles for you: upload Thai audio or video, or paste a link, and it transcribes the Central Thai speech, splits it into properly timed cues, and exports an SRT or VTT caption file in minutes. It inserts the word breaks Thai script leaves out so cues land on sensible boundaries, not mid-word. Thai is detected automatically. Your first 60 minutes are free, no card.

How thai subtitle generator works

01

Upload or paste a link

Add a Thai recording or paste a link – any audio or video format works.

02

Auto-generate captions

Pepys transcribes the Central Thai and splits it into timestamped subtitle cues.

03

Download SRT/VTT

Export a ready-to-use SRT or VTT file with the timing already set.

Captioning makes Thai content travel – a cooking channel reaches deaf viewers, a corporate town hall gets searchable, a short film qualifies for a festival. Pepys reads Thai audio or video, transcribes the Central Thai speech, and turns it into timestamped SRT or VTT cues you can drop straight into your player or editor. Where most caption tools choke is the cue split: because written Thai has no spaces, a naive splitter slices a caption mid-word. Pepys finds the word boundaries first, so each cue breaks where a Thai reader would expect it to.

Tone is the other catch – Thai distinguishes words by five tones, and a caption that mishears the tone changes the line, so Pepys is built to keep them straight. Thai script, with its stacked vowels and tone marks, renders cleanly in the exported file, and you can fix any cue inline before downloading. Want a bilingual track? Translate the captions into another language too. Your first 60 minutes are free, credits never expire, and we never train on your audio.

Clean paragraphs. No more um's and ah's.

The left is what Pepys hands back – logical paragraphs with the filler stripped out, punctuated and readable. The right is the raw, one-line-per-segment dump most transcribers leave you with.

um so yeah everyone keeps telling you to like lead with your best line right but uh honestly if you give away the whole answer in the first second you know there's basically no reason for anyone to keep watching so the hook isn't kind of the smartest thing you say it's like a loop you open that they need to close and um that's the part that actually keeps people around

Thai subtitle generator – questions, answered

How do I generate Thai subtitles?

Upload Thai audio or video, or paste a link – the first 60 minutes are free, no card. Pepys returns downloadable Thai SRT/VTT captions in minutes.

SRT or VTT – which should I pick?

Both come out of Pepys. SRT is the most broadly supported across players and platforms; VTT is the web-native format for HTML5 video. Export whichever your setup expects.

Are the captions burned into the video?

No. You get a downloadable sidecar caption file – an .srt or .vtt – that you load alongside the video. The picture itself is untouched.

Does Thai script display correctly in the file?

Yes. Thai characters, including stacked vowels and tone marks, render properly in the exported SRT/VTT, and you can edit any cue inline before downloading.
