Does Joker have voice acting outside the main campaign?

About a month ago, I finished Batman: Arkham Knight on PC (the game was playable enough for me). I finished the story mode quite quickly, only having finished Hush and some partial missions before the final mission in the campaign.
After watching some scenes from streamers, it appears that I finished this story line too soon, however, because I saw some Joker voice acting near a Militia Watch tower that I think I missed.
The Joker voice acting in Knight, to me, was one of the highlights of the game, and I'm worried that I missed some of it. I was already planning on doing another playthrough of the game later this month, after the first major patch for PC so I can hopefully play the game in a more intended fashion. Is there Joker voice acting outside of the main storyline?
