Topic: How Lyrics are analyzed???
I'm trying to understand according to what I see in the program's behavior.

The Lyrics are calculated separately from the Stems?
Are they calculated simultaneously?
Are they calculated immediately after the Stems?

I notice that sometimes when I load the song, I click play and until it reaches the first Lyrics they have been calculated and I see the Karaoke normally.
Other times the video freezes and only shows the small waiting circle until it calculates.
And some other times I skip directly to Lyrics and they play immediately, without even a second, which means that they are already calculated somehow. This is the first time I have loaded these songs.
I have the feeling that because they are some well-known songs, maybe they have already been calculated by other users of the program and exist in some central VirtualDJ database and it pulls them directly from the Internet.
I am confused about the process.

Stems speed I have is about 6x-7x

That is correct.

And I'm talking for Greek songs
 

Doesn't matter if they are Greek or not.
If the AI model has analyzed a track for Lyrics before, then the result is cached and pulled via internet.
If however the track has not been analyzed by the AI model before, then it will get analyzed at that very moment (assuming you are a PRO user and you have stems enabled).
