How to force narrator to read a text before another text

Hi,

       Currently I have a wpf user control that has a stackpanel and in the stackpanel there is a textblock and a few buttons. The focus is on the button and narrator reads the name of the button but I want the screen reader to read the text from the textblock too.

        Any idea on how to do force screen reader to read a text without focusing it?

Thanks,

Hoay
