Korean Subtitle Generator

Korean is spoken quickly and edited faster. The style that dominates Korean YouTube and Shorts has jump cuts every few seconds, speech that runs at a high syllable rate, and constant switching into English for emphasis and slang. Subtitles have to keep pace with that, which means short lines, tight timing and a transcription that does not stumble every time the speaker says a brand name.

Hangul itself is regular, but the conventions around it are not. Spacing between words follows rules that even native writers get wrong, and a subtitle with wrong spacing reads awkwardly. Particles attach to the noun; auxiliary verbs are spaced or not depending on the construction. The transcript applies the standard rules, which is one of the things that separates a clean Korean subtitle from an obviously automatic one.

Register matters because Korean encodes it in every sentence ending. A transcript that flattens 반말 into 존댓말, or the reverse, changes the tone of the video. The speaker's register is preserved as spoken, and English borrowings are written in Latin script where they were used, so the subtitle reads the way the video sounds.
