Good news - it doesn't work. So you've saved yourself a fortune.
That's a recurring theme in many of the newer features by the way. Things either don't work properly or don't do useful tasks. The headline "multiple speaker detection" promises wonderful things, separating several speakers on to their own layers. In fact it just translates them badly to text, much worse than Microsoft, and that information can't be usefully used anyway. If you were searching for other instances of the word "disappointing", it would be great to highlight the word and cycle through the alts in the file and then replace. You can't do any of that.
