The Nordic Society for Invention claims to have developed a working prototype of a device called No More Woof that reads a dog's brain signals and converts them into English phrases that match the dog's emotional state. Phrases include: "This is splendid!" "Leave me alone." "I am so very weary." "Who are you?" "Em, why are you guys leaving?" "Is that really you?" "Night-time!" "He must be a very nice animal."
