I confirm that I have modified the text speed in the game.  Not in the cinematics that are linked to the music. It is necessary to start a new game to notice the difference.

Now they go a little bit slower. Especially the very short sentences have increased the minimum time they are displayed on screen.

I hope this helps and that everyone can read all the texts well. I can't make the texts skip manually because it would mess up some of the time-dependent puzzles in the game.
