"in the US" :(

We also still are waiting, for 10+ years for Siri in european languages. We have a lot of users e.g. in Poland, we can dictate in polish, but Siri still can't call a contact, because she doesn't understand names...

Tip: you can add a 'Phonetic' name to a contact, and Siri will try to use it.

So you can do stuff like:

Mieczysława -> Mee-etchiss-wahva Krzysztof -> Kzhyshtof Świętopełk -> Shvee-entoh-pehwk

It's still a bit hit and miss, but works quite well with diminutives:

Mieczysława -> Mietka -> Mee-etka Krzysztof -> Krzysz -> Kzhysh Świętopełk -> Świętuś -> Shvientush
