Upload a Khmer video or audio file, or paste a link, and download timed subtitles in Khmer script: SRT for YouTube and video editors, VTT for web players.
How it works
Drop a file, or paste a public link from YouTube, Google Drive or a podcast feed. Files over 500 MB continue on the upload page, up to 10 hours or 5 GB.
Read the first Khmer cues against the audio. Correct a line on the transcript and the subtitle file carries the correction.
SRT for YouTube Studio and video editors, VTT for web players. TXT, DOCX and JSON come from the same transcript.
What to expect with Khmer
For a transcript rather than subtitles, see transcribe Khmer, Khmer audio to text and Khmer YouTube video to text. For subtitles from any YouTube link, YouTube to SRT; for any file, the SRT generator.
Captioning Khmer
Khmer writes words without spaces between them; a space marks the end of a phrase. A player wrapping a long Khmer cue has no word boundaries to use, so it may break inside a word. The text's own word segmentation is honest but imperfect, so read long cues on screen and split them by hand in your subtitle editor where the break lands badly.
Khmer stacks the second consonant of a cluster below the first (the coeng forms) and places vowel signs above, below, before and after. A cue can be tall, and a player without Khmer shaping draws the parts in a row. Use a Khmer font such as Noto Sans Khmer, Kantumruy Pro or Battambang and give the line extra height.

Each cue is a phrase from the transcript with its start and end time. Most run a few seconds. A passage spoken without a pause can come out as one long cue of up to about half a minute, so split those in your editor if your platform wants two short lines at a time.
Cue times are taken from the recording itself, so the file lines up with the video or audio you uploaded. If you trim the start of the video afterwards, shift the cues by the same amount in your editor.
Open the transcript, correct a misheard name or number on its line, and the SRT and VTT you download carry the correction with the timing unchanged.
You get the subtitle file. Fonts, colours, position and captions drawn into the picture are done in your video editor or player, which reads this file.
Up to 10 hours or 5 GB per recording. The box on this page takes files up to 500 MB; larger ones continue on the upload page. 99+ languages, detected automatically.
Speakers are identified and named in the summary, key quotes and chapters. The cues in the subtitle file carry the words and their timing only.
