What are the two words

that the speech giver said in this video from 01:39-01:41?

http://www.ted.com/talks/kevin_slavin_how_algorithms_shape_our_world.html

The sentence goes as "They acuire the sensibility of truth, because they repeat over and over again and they kind of oxify and coxify"

Well, the last two adjectives were definitely misinterpreted,

because I can't find any result in any dictionary,

neither can I interpret them in any other way,

can anybody please help correcting me here?

Thanks so much in advance
