Wowwwww, I understood nearly every word of that

Лена: no need for the comma there; just put "I don't think that they speak" or even just "I don't think they speak" (may not be technically correct, but everyone uses it).
It's a nightmare when business gets down to whether or not should I put a comma in some part of an english sentence. The rules in russian and english are absolutely different so (i'm thinking now about the comma before "so" ) it's always hard to make a correct choice.
I can see that. You use commas in lieu of the connective (don't know the proper term) 'that', don't you, e.g. "я знаю, я не красивый"? We cheerily ditch 'that' entirely from subjunctive sentences ("I know that I am here" -> "I know I am here" [-> "I know I'm here"]).
