This is fun so I will break down her speech patterns a bit.
1) She almost never uses contractions.
Stuff like I won't, we didn't, they haven't, etc. are things that she won't say. She will always say I will not, we did not, they have not, etc.
This was even used in the story one time.
In this page Gambit notices that this isn't the real Laura but Miss Sinister in disguise because she was using contractions which the real Laura doesn't do.

2) Questions or statements that can be answered by just saying yes or no, will be answered that way for the majority of the time.
"Are you OK?" "Yes."
"Do you need something?" "No."
3) She very rarely speaks more than one or two sentences at a time. She can speak more but those situations are very rare and when she does that than it is mostly because she is explaining something.
Here is another example that illustrates all three points.

Now there is likely more and if somebody wants he can add to that. It's 6 am here and Im tired so I could have missed something.
