A patent filed in April 2016 reveals Microsoft’s attempt to make Cortana (the intelligent personal assistant created by Microsoft) more human-like in the responses given to Windows users.

This patent alludes to Cortana’s personalised greeting system being personalised to the user and more natural to interact with.  A range of different greetings will be used depending on the time of day, the location, weather, or congratulating the user on special occasions, sports results that are known to be of interest to the user etc.  The system will work by utilising data on the user (drawn from searches, emails etc).  The more data available, the more personal the user’s experience can be.
