Cortana might not support your native language though - I'm not up to speed on what languages are supported, maybe only English.

Cortana is only currently available in these languages and only works if region, language and speech language are set the same. Source



There are Alpha versions for Australian, Canadian and Indian English (but that might just be for phone). Source
