Is dialogue procedurally generated?

I made an effort to learn a lot of words to be able to communicate with the Korvax, but I'm noticing that even though my character understands all of the words, they're not perfectly coherent or grammatically correct by a longshot. For instance, a Korvax NPC asked me:

ahem. korvax entity help?

Is the grammatical structure like this because dialogue is procedurally generated, or is there a special piece of equipment/milestone I need to acquire in order to improve translation?

Dialog is procedurally generated but not in the same sense that the planet or and structures or fauna and wildlife are 'procedurally generated.' In the context you're asking - yes, all evidence points to that it is but other courses of information decrease the depth that procedures exist.

Syntax is procedural within a limit, structure is procedural and identical for all members of the same race, game-wide; dialect between races will change game to game. Their common bond is a predefined dictionary.

Your image example "Ahem. Korvak entity help?" will always translate to this from the original words by the Korvak.

Nicholas Tan's blog post on GameRevolution claims he's discovered that only a little more than 400 words total exist between the three races and Atlas. Additionally, a few online translators exist like this one for the Gek.

But no milestone or other item in the game corrects the grammar to something to doesn't feel jerky and procedural generation isn't necessarily the cause of what you see, rather it seems to be just how the races were written by design.
