Siri struggling to read "foreign" languages
I live in multilingual environment, I like my phone to be set to use English, but I regularly receive messages in French, German and Polish. Anticipating some difficulties I've never used Siri till now.
Now I'm compelled by the car manufacturer to use Siri in the car - otherwise they cannot connect. Well, today mister Siri - I think I managed to change to female voice already - read aloud a message, which was a pure nonsense (it was really a compound of irrational sounds meaning completely nothing in any language). After arrival I checked and it was a perfectly correct French message (which takes a blink of an eye to be read, btw. so I could do it on the car screen without risking anything whereas grabbing for the phone is a no go).
Now, I know iphone is American, but I cannot imagine there are no bilingual communities in the U.S., aren't there? So there has to be a way for Siri to use another language. I mean not simultaneously, but at least for reading the messages? On the contact basis perhaps? In most of the cases that would do.
I haven't found the setting though. Or is there some "automatically detect changes" or similar setting hidden somewhere?
I would greatly appreciate any help.
