"I think the two main characters get recruited for something. but the main thing I remember is them having to go into secret silent rooms to speak freely, so either everyone can hear everyone's thoughts, or I know a book exists where you can only say a certain number of words per day. Essentially heavily restricted free speach. i thought it was maybe Scythe or The knife of never letting go but I dont think it is."
