Method to trigger speech dispatcher to read selected text with keystroke

I am looking for a method to use speech dispatcher to read the selected text by triggering a keystroke. For example, selecting a few paragraphs of text and hitting Meta + Space and it passing a command spd-say [selected paragraph].

The KDE keyboard shortcuts menu in system settings has the ability to run a custom command by keystroke, but I do not know how to make it pass the selected text.

I am getting close here but can’t get it to work yet.

wl-paste --primary | spd-say -e will speak whatever is selected, but I cannot get the keyboard shortcut to execute this.
