Future ATC possible?

[kapitan 90]

If its all text-to-speech
I guess a human voice only records the alphabet letter sounds, 
It shouldnt be very difficult to have ATC in other languages?

And my second thought, why cant Microsoft use a version of Cortana specifically oriented for aviation according to the sim parameters?

Then she/he could give you instructions for the runway and also freely reply to any question.
Like, "how are you today" 
"Im fine Sir" (instead of your name which would be non formal)
You could declare an energency and she gives straight vectors to the nearest airport

Tell you the weather for any place you ask

They could get a copy of the Cortana knowledge base (which they own) and customize her specifically for aviation turning her into an ATC controller, instead of searching the web, she would analise your position and logical responses according to what you want to do.
