The audio doesn’t match the text.
Does it say “fallecido”? I couldn’t find “Se dice que ha muerto” in any collection, but I did find “Se dice que ha fallecido”, which has the former Tatoeba sentence as its source, but it seems to have been changed here at Clozemaster.
That looks like an arbitrary change to me, especially since the sentence is part of the “500 most common” collection, and “fallecido” is much less common.
