SubSync, or Subtitle Speech Synchronizer, is a very handy tool that automatically synchronizes movie subtitles, so you don't have to adjust them manually. The developer provides binaries for Linux (Snap) and Microsoft Windows.
The automatic movie subtitle synchronization is done by analyzing the audio track, even if it's in a different language than the subtitle file. This is done by using dictionary files that are automatically downloaded by Subtitle Speech Synchronizer, supporting a large number of languages.
