New to Bazarr

Well, I think this question might be a bit niche since I haven't seen anyone asking for things in Spanish.

But I have a doubt with Bazarr, I have configured it to look for subtitles in 2 languages in Spanish (Spanish and Latin Spanish) and many times it finds the subtitles for the series but most of the times it is not well synchronized; I would like to know if there is a way to synchronize it automatically so that it matches the voices or not.

I have also read a lot of what they say about making subtitles with AI. I would like to know if there is a way to do it that way too, because I have old series that I can't find subtitles on any platform.
