I don't think so, but if you can't understand what they are saying, who cares? I use it most of the time when watching movies. It seems like all they do anymore is mumble.
Thanks for posting on the Community!
The dialog mode essentially adjusts the EQ and compression levels of the soundbar. It will roll off some of the bass which will remove the "muddiness" in the center channel vocal track as well as increase the level of compression to help level off other sound effects like soundtracks and explosions.
Let us know if you have any further questions!
