Speech to Text feature

[Orion72]

I'm having trouble with the speech to text feature. I push the button and say "Text Angie" the problem i am having is it pulls up the two Angies in my contact list. Even when I use Angies last name it pulls up her and her brother (whom is in my contact list) I've tried to delete the other Angies number in my contact list and in my google contacts, but her number still shows up when I try the Speech to text feature. How do I use it for the one person and no other?
