Cortana thinks my wife is someone else. How do I correct her?

[WPCentral Question]

Cortana thought I said "EM" instead of "Mai". Now she thinks my wife is "EM" and can't find the contact info. I can't ask her to call or text "my wife" since and I don't know how to correct Cortana.

 

[RumoredNow]

Open Cortana > Hamburger menu (3 horizontal lines stacked on top of each other in the upper right) > inner circle

Long hold on a name you want to get rid of > tap Remove in the pop up

Tap a name you want to refine > edit the nickname slots

Tap the + symbol at the bottom of the screen to select a Contact to add to your Inner Circle
