You can't do it. The only spoken lines are during encounters, and they're pretty one sided.
Really would like to see this added somehow.
You can add patrols and ambushes where they can talk. You can also have defendable items talk and anything guarding a ally/rescue option. You can also add a defeat a boss where they talk. Those options are all located under I think boss text or dialogue or settings. Hope that helps.

As soon as you write the text, test the missions through a few times! The lines are sometimes talked over each other when objectives spawn too close to each other (try using a variety of Front/Middle/Back).
Also, when there is Inactive Text and Active Text, right now all four lines tend to pop up all at once, even if the player is nowhere near them. Until that's fixed, write the "Active" text to work whether the player sees them or not.
Example - Cause of How Some Silly Stealed My Wings has a Battle "Inactive/Active" text objective right when you enter the first mission, so you can see very quickly what I'm talking about.
