Why almost no dirty talk?

I wonder why there is so little dirty talk in Lp scenes? There is some in the one with american actors, but thats mostly lame also.
I would like to se more of self degrading dirty talk and self name calling from the girls in the porn. Not only at the beginning but during the fucking and especially the deepthroating.
If the girls is bad on english and bad remember, why not write the lines to say on placard to read, who camera man ore some one else could hold up "behind the scene", for the girl to read out.
