I’m not sure what is on your phone. But to get Cortana works as U.S. version. You need to configure the settings properly:
1. Set Language to English (United States). You may have more than one languages being set. In that case, you need to put in at the top of the list, which makes it default. To do that, tap and hold on English (United States), a context menu pops up. Tap “move up”. Repeat this process repeatedly until it reaches the top. Or you can just remove the languages you don’t need. The languages being shown here do not reflect keyboard input method; merely display languages.
2. On region, set Country/Region to “United States” and Regional Format as English (United States).
When these settings are configured, you should be able to use Cortana. You can chit chat with it by asking some silly questions like “Do you like me?”
