What do you know about Cortana and other languages?

[Dennis Bakker]

One of the key functions in Windows 10 is Cortana and Microsoft let's everybody know how good she is as a smart assistant. But why does Microsoft lacks to bring Cortana to other languages? Dutch is not a real widely spoken language, but Google and Siri do understand and speak Dutch, and the same is probably true for many other languages.

I try to speak English to Cortana, but it's almost impossible to let her understand Dutch names.
