is there an AI tool for automatically fixing the timing of the lines

[cns00]

I have subtitle files for movies and the timing is bad and lines show before someone starts speaking and they stay after a person stops speaking. I need the lines to show exactly when someone starts speaking and go away exactly when a person stops speaking. Currently I am manually editing the timing of the lines and it's tough work.

is there an AI tool that can automatically fix the timing? I found AutoSubSync and I tested it. The lines are still showing for some time after the person stops speaking. I need something which is more accurate.
