lyric-translator-ko2en

An LRC file with Korean lyrics is required to generate interleaved English translations. You provide the time-stamped LRC file, and the tool automatically outputs an alternating source-then-translation format with identical timestamps.

Existing English lines, metadata tags, blank lines, and sound effects remain completely untouched during Korean lyric translation. The tool only targets Korean lines, preserving all non-Korean content and original LRC timestamps without modification.

The tool enforces consistent chorus translations by providing stable English translations for repeated Korean lines. This ensures uniformity across the entire LRC file, so identical Korean lyric lines receive the exact same English translation every time.

Vocalizations are preserved and code-switching lines are handled according to strict insertion rules during translation. Each generated English translation is capped at 18 syllables, maintaining a concise rhythm that matches the timed LRC structure.

Each English translation inserted into the timed LRC file is capped at 18 syllables. This limitation ensures the translated lines remain concise and rhythmically aligned with the original Korean lyrics for karaoke and reading purposes.
