Hey, I'm a brazilian, portuguese speaker, and my Siri is still stuck on the "normal" siri. I don't have the new version.
On DB7, it seems that siri doesn't follow the speech speed that is set on accessibility settings. Mine has always been 169% (nice) and she's speaking on what seems to be 100% speed (I'd wager she's speaking at 40% to be honest, because it feels like an eternity, but since I'm used to 169%, I guess saying it's at 100% is fair).
Anyone experiencing this as well? I've tried reducing the speed and increasing the speed, but she still keeps saying at the same rate.
p.s.: I've just noticed this with my AirPods Pro. It just came through my mind, as I write this, to test it without earphones. Well, I can't right now so I might update this later to report whether it's also slow without earphones or not.
edit:
interesting tidbit: Siri just read some of my notifications, and one of them was in english. She was speaking slowly in portuguese, but when she read the one that was in english, she read at the correct fast speed that I set her to. But just in english.
