About Thai transcription

Thai (ไทย) is written in the Thai script and spoken principally in Thailand. Subtitles generated here come back in that script, as ordinary written Thai, ready to use in an SRT or VTT file.

Thai is written without spaces between words and is tonal, so segmentation happens during recognition rather than afterwards. The script has no capital letters and no full stops, which makes sentence boundaries in the transcript a judgement call worth reviewing.

What a Thai subtitle file looks like

Four lines as they come out of the exported SRT, in the Thai script with the timings taken from the speech itself.

1
00:00:01,000 --> 00:00:03,240
ขอบคุณทุกคนที่มา

2
00:00:03,600 --> 00:00:06,120
ทุกคนได้ยินผมชัดไหม

00:00:06,480 --> 00:00:09,300
วันนี้ก็มีเพียงเท่านี้

Where Thai words begin and end

Thai is written without spaces between words, so segmentation is part of recognition rather than a tidy-up afterwards. This is why word-level timings matter more here than in a space-separated language — the boundaries are inferred, not read off the page.

Subtitle lines are worth spot-checking at their start and end, which is where those decisions land.

Register in a Thai transcript

Thai marks politeness grammatically, so the level a speaker uses carries real information about who they are addressing. Transcription preserves it rather than flattening everything to one register.

That makes a transcript useful as a record of how something was said, not only what was said — worth knowing before you edit it toward consistency.

Tone and recording quality in Thai

Thai uses pitch to distinguish words that are otherwise the same, so recognition leans on tone as well as on the sounds. Background music costs more accuracy here than it would elsewhere, because it competes with exactly that cue.

Where tone is misheard the result is a real word rather than obvious nonsense, so errors read as plausible and are worth a deliberate check.

What people caption in Thai

The Thai material that comes through most often is vlogs, news, drama clips and educational video. All of it works the same way — upload the file, check the transcript, export the subtitle track.

Getting a better Thai transcript

• Set the language to Thai rather than leaving detection on, particularly for clips under a minute where there is little audio to judge from.
• Upload the highest-quality audio you have; compression artefacts cost more accuracy than most people expect.
• Check proper nouns, place names and numbers first — recognition errors concentrate there.
• Read the transcript before exporting. Thai subtitles are editable up until you download them.

Thai subtitles in another language

The same Thai audio can produce subtitles in any of the 76 supported languages instead of in Thai itself. English is the most common target, but every pair works, and the translated file keeps the original timings so it drops onto the same video unchanged.
