This isn't possible in DAZ studio. There are also no plugins for DAZ Studio that can add bubbles.
You can use a software like Sony's Movie Studio, which allows adding overlay bubbles.
Alternatively, you can render the movie to image series, then add a speech bubble to every image by an image editor like GIMP or Photoshop, and then use a software like Movie Studio, or freeware solutions to merge the edited image series.
Renderosity has a couple of free speech bubble objects for download. You would still need to add your own text via a texture and it would be a good adia to set the parameters of the speech bubble to "point at" your camera.
