I think the Google voice recognition service (triggered by "Ok Google") on my phone already does something similar. When I used to say to call a particular person, it would ask "which number, home or mobile?", for example. Over time, I usually always ask for the same number for a particular contact (mobile), and it learned that when I ask for the first name of the contact, it usually always means a specific contact. So whereas initially I had to say the full name and pick a number, now all I say is "Call <first name>" and it starts dialing the exact contact I wanted. It also knows that this first name is my wife... so I can even say "call my wife" and it also works. This lends credence to the model you're describing, and maybe that's exactly how it will work in the future. I think machine learning sorts this out quite well.
